Ada (played by Vicki Lewis) – George's secretary at the New York Yankees. In the episode "The Secretary", George does not want to hire an attractive secretary so he could focus on his work, and in the interview process turned down a few women because they were so attractive. George ultimately hired Ada, whose efficiency impressed him. One day at work together, George becomes attracted to Ada, and the two make love. While having sex George blurts out that he's giving Ada a raise. Ada receives the raise, but it turns out that her new salary is higher than George's, much to his annoyance. In "The Race", Ada overhears George on the phone with a woman he met through The Daily Worker, and believes George is a communist. She tells Steinbrenner about this but instead of reprimanding him, Steinbrenner sends George to Cuba to recruit Cuban baseball players.
Allison (played by Kari Coleman) – George's ex-girlfriend who he claims is obsessed with him, proven by the fact that she threatened to kill herself if George broke up with her. In the end of the episode "The Smelly Car", Allison compliments the vest of George's other ex-girlfriend, Susan, with whom she is seen watching the pilot program in a later episode, "The Pilot".
Babu Bhatt (played by Brian George) – An immigrant from Pakistan who owns the nearby "Dream Café". Jerry seems to mess up his life at every turn, by giving bad business advice on his restaurant and by not passing on his immigration notice that is accidentally delivered to Jerry's mailbox. Babu thinks that Jerry is a "very, very bad man" (wagging his finger).
Barbara "Babs" Kramer (played by Sheree North) – Cosmo Kramer's mother. She used to be a matron in the women's restroom at a restaurant, but was persuaded by Kramer to resign from that job and pursue an undefined venture with him. Although mentioned in "The Nose Job", her first on-screen appearance is in "The Switch" where she unintentionally reveals Kramer's first name to be Cosmo and has a sexual encounter with Newman. Babs was once addicted to alcohol and drugs, claiming to have been "clean" for two years.
Beth Luchner (played by Debra Messing) – A physician who appears in "The Wait Out". Married first to David Luchner. Later appears in "The Yada Yada" with her new husband, Arnie.
Bob and Ray/Cedric (played by Yul Vazquez and John Paragon) – A hostile gay couple who accost Cosmo Kramer in "The Soup Nazi", "The Sponge" and "The Puerto Rican Day". They are widely known as "street toughs". They steal Elaine's armoire that Kramer is guarding in "The Soup Nazi", verbally and physically attack him for not wearing an AIDS walk ribbon in "The Sponge", and attack him when he accidentally sets fire to a Puerto Rican flag. John Paragon's character is credited as "Ray" in "The Soup Nazi", but is addressed and credited as "Cedric" in "The Sponge".
Bob Cobb (played by Mark Metcalf) – A conductor who prefers to be called "Maestro" and has a villa in Tuscany. Cobb introduced Kramer and Frank Costanza to the trick of taking their pants off before sitting so the pants will "keep the crease"
Carol (played by Lisa Mende) – Mutual friend of the main characters. Carol and her husband, Michael, lived in the Hamptons, and she kept insisting that the group come out to see their baby. She had two babies, an unnamed daughter who was dropped by Kramer in "The Boyfriend", and a son named Adam (although unseen) who was introduced in "The Hamptons". Kramer once likened the cute baby to Lyndon Johnson while Elaine compared the ugly one to a Pekingese. Carol is notable for her nasal voice and her memorable quote: "You gotta see the baby!" or "You gotta have a baby!" in "The Soul Mate". Her final appearance was in "The English Patient", when she and her friends shunned Elaine after she showed her dislike for the film of the same name.
Conrad: (played by Stephen Lee) – Also known as Connie or Con. Appears in "The Nap" as an indecisive contractor hired by Jerry to update the kitchen in his apartment. He also helped George sleep under his desk at Yankee Stadium.
Counter Woman: (played by Kathryn Kates) – In the episodes "The Dinner Party" from season 5 and "The Rye" from season 7, the Counter Woman works at Schnitzer's Bakery. In season 5, the Counter Woman ignores the fact that Jerry and Elaine came in ahead of David and Barbara Benedict, a couple on their way to the same dinner party who purchase the last chocolate babka. The Counter Woman makes another appearance and is seemingly happy to give her last marble rye bread to Mabel Choate (a woman who was ahead of Jerry).
Dana Foley: (played by Gina Hecht) – A friend of Elaine's who works as a therapist, and gives George several therapy sessions. She appears in "The Pick", "The Shoes" and "The Pilot". George walks out on her after she modestly criticizes the script of "Jerry".
Deena: (played by Mary Jo Keenen) – A childhood friend of George who thinks that he is mentally unstable after she repeatedly catches him in bizarre situations. First, in "The Gum", she notices striking similarities between George's behavior and that of her mentally unstable father (affectionately known by all as 'Pop'), that being "nervousness, irritability, and paranoia". Her suspicions are heightened when she sees him walking down the street in a King Henry VIII costume telling people he just left the "institution". Then in "The Doll" she catches him in the coffee shop, alone and screaming at a doll that looks like his mother. Finally in "The Bottle Deposit", she is visiting her father at the mental asylum when she runs into a hysterical George (who was mistakenly sent there by Mr. Steinbrenner). She ignores his pleas to help him escape believing that he is finally getting the help he needs.
Dolores (played by Susan Walters) – One of Jerry's many girlfriends; he can't remember her name, only that it rhymes with a female body part ("clitoris" doesn't occur to him and his best guess is "Mulva"). ("The Junior Mint"). Jerry reunites with her in "The Foundation".
Donald Sanger, aka The Bubble Boy (voiced by Jon Hayman) – Jerry agrees to visit a bubble boy, who lives in a hermetically sealed bubble due to a compromised immune system. Jerry gets lost on the way and George and Susan end up meeting the bubble boy but find he is a bratty spoiled kid. George and Donald fight over a typographical error on a Trivial Pursuit card, which says the Moops (rather than the Moors) invaded Spain. The fight results in the boy's bubble being popped.
Dr. Reston (played by Stephen McHattie) – Elaine and Crazy Joe Davola's therapist. Elaine dated him and went on a trip to Europe with him ("The Pitch" and "The Ticket").
Earl Haffler (portrayed by O'Neal Compton) – Appeared in "The Diplomat's Club". He made bets with Kramer on which planes coming to the airport would arrive later than scheduled. Earl appears again in "The English Patient", where his deal with Kramer to buy "Cubans" falls through and he orders Cosmo out of his office.
Father Curtis: (played by Henry Woronicz) – A priest who consults with Elaine and Puddy on their relationship in "The Burning", and with Jerry on his encounter with Tim Whatley in "The Yada Yada".
Franklin Delano Romanowski (played by Mike McShane) – Also known as "FDR", Franklin is another of Kramer's eccentric friends. In "The Betrayal", he uses his birthday wish against Kramer as the result of a grudge held after Kramer struck him in the back of the head with a snowball. The same actor also appears briefly in "The Wizard" as the hot dog vendor talking with George. Although his character's name is not revealed, he is presumably the same character because he was seen selling hot dogs in "The Betrayal" also. He is mentioned by Kramer in several episodes, usually in some outrageous anecdote.
Fred Yerkes: (played by Fred Stoller) – Elaine had met him at a party some time before, but his lack of recall for the meeting mesmerizes her. He appears in "The Secret Code" in Season 7.
Gary Fogel (played by Jon Lovitz) made his only appearance in "The Scofflaw", although he is mentioned again in "The Face Painter".
Izzy Mandelbaum (played by Lloyd Bridges) – Fellow resident of Jerry's parents in Del Boca Vista in Florida; head of family-owned Magic Pan crepe restaurants. His favorite saying is "It's go time!" He is obsessed with his physical fitness. In "The English Patient", he throws his back out twice after being "challenged" by Jerry. Izzy also appears in "The Blood".
Jake Jarmel (played by Marty Rackham) – An author that Elaine dated for a period. Dislikes using exclamation marks in "The Sniffing Accountant". Broke up with Elaine after she bought Jujyfruits immediately after hearing he was in a car accident ("The Opposite"). Bought his glasses in Malaysia so no one else would have a pair like them ("The Scofflaw"). He started a fight with Mr. Lippman when he noticed that Lippman had the same "unique" frames as himself. The actor who plays Jake Jarmel also appears as an LAPD officer in the episode "The Trip".
Jenna (played by Kristin Davis) – Jerry's girlfriend on Season's 8 "The Pothole". She later dates Kenny Bania, as shown in Season 9's "The Butter Shave".
Jiffy Park Guy/Jiffy Dump Guy (played by Chaim Girafi) – An attendant at Jiffy Park who may or may not be utilizing George's car, along with other cars parked on the lot, as a den of iniquity for prostitutes to conduct their business in the episode "The Wig Master". His second appearance was in "The Muffin Tops" where he portrayed the late-night operator of sister-company Jiffy Dump who steadfastly refuses to accept trash bags of discarded muffin stumps.
Joe Temple (played by Robert Hooks) – A family man with whom George watches Breakfast at Tiffany's in the episode "The Couch". Joe dislikes George after he spills grape juice on his couch. Joe also appears in "The Diplomat's Club", in which George tries to watch another film with him.
Joel Rifkin (played by Anthony Cistaro) – Elaine's ex-boyfriend who coincidentally has the same name as serial killer Joel Rifkin. His first and only appearance was in "The Masseuse". Joel and Elaine break up because they cannot decide on whether his new name should be Remy, Alex, or Todd.
Joey Zanfino (played by Todd Bosley) – A 9-year-old boy who lives in the same apartment building as Jerry, Kramer and Newman. Joey's mother asks Kramer to babysit him but due to his staggering walk (caused by his ultra-tight jeans), Joey mistakes him for Frankenstein's monster and runs away. By his second appearance, they are friends and go to the same karate class, despite Kramer being many years older. Joey and his friends later beat up Kramer because he beat them up in karate. He appears in both Season 7's "The Wait Out" and Season 8's "The Foundation". Joey is also mentioned in Season 9's "The Serenity Now", as he and his friends fight with Kramer.
Karen (played by Lisa Edelstein) – George's girlfriend in "The Mango" and "The Masseuse".
Karl (played by Ellis Williams) – A professional exterminator that Jerry hires to rid his apartment of fleas in "The Doodle". In "The Diplomat's Club", George befriends Karl in an attempt to prove to co-worker Mr. Morgan that he is not a racist.
Katie (played by Debra Jo Rupp) – Jerry's annoying agent. First in "The Diplomat's Club", she invites the pilot of the plane to Jerry's comedy routine and tells Jerry not to be nervous, which makes Jerry extremely nervous and causes him to "bomb". Next in "The Abstinence", Katie gets Jerry an entire assembly at his former junior high school after Jerry is "bumped" at Career Day by a zoo worker. Jerry is unprepared for the assembly, and after he tells his first joke, he is met with boos. Consequently, David Letterman cancels Jerry's appearance on his talk show after hearing about his poor performance at the assembly.
Keith Hernandez (played by Keith Hernandez) – fictionalized version of the baseball player, who befriends Jerry and later dates Elaine in "The Boyfriend".
Kevin (played by Tim DeKay) – Elaine's one-time boyfriend, most notable for being "The Bizarro Jerry". He dates Elaine in two Season 8 episodes, "The Soul Mate" and "The Bizarro Jerry".
Lannet (played by Amanda Peet) – Waitress Jerry dates in "The Summer of George" episode. She lives with a man which confounds Jerry as to her relationship with him.
Leslie (played by Wendel Meldrum) – Kramer's "low-talking" girlfriend, a clothing designer who designed the new puffy shirt featured in "The Puffy Shirt" episode. She also appeared in "The Finale" as a witness in the trial, but her testimony is not accepted because no one in the courtroom can hear her. Jackie Chiles tells Judge Arthur Vandelay to either get Leslie a microphone or they should move on with the trial.
Lindsay Enright (played by Jessica Hecht) – An ex-girlfriend of George's who was in a book club in "The Couch". They were supposed to read Breakfast at Tiffany's, but George watched the film instead and made incorrect statements about the book. She then appears in "The Gymnast".
Lloyd Braun (played first by Peter Keleghan, then by Matt McCoy) – A childhood friend of George. Estelle Costanza used to badger George with questions such as, "Why can't you be more like Lloyd Braun?" In "The Non-Fat Yogurt", Lloyd works for New York City mayor David Dinkins. After Lloyd passes along Elaine's suggestion that everyone in the city wear name tags, he is ridiculed, fired, and has a nervous breakdown. (Two versions of the episode, which aired two days after the real mayoral election, were shot. If Dinkins were to have won the race, Lloyd would have been depicted working for mayoral candidate Rudy Giuliani.) After spending time in a mental institution, Lloyd helps Kramer gain historical status for a movie theater in "The Gum". In "The Serenity Now", Lloyd works for a short time for Frank Costanza as a computer salesman. In an attempt to outsell Lloyd, George purchases a large number of computers with the intent to return them once Lloyd has been fired for poor performance. It is later revealed that all of Lloyd's sales were fabricated and that Frank complied with the ruse in order to give George someone to compete against. Larry David named the Lloyd Braun character after the real-life Lloyd Braun, who was David's lawyer and manager.
Lt. Joe Bookman (played by Philip Baker Hall) – A library cop who pursues Jerry because of an overdue copy of Tropic of Cancer, which Jerry had borrowed in 1971. Bookman's dedication to his job and coincidental surname are cause for Jerry's dismissive attitude toward him. Bookman's character is defined by his deadpan delivery (a parody of Sgt. Joe Friday in Dragnet), and his tendency to flip his trench coat dramatically during interrogations. Appears in "The Library" and "The Finale, Part 2".
Mabel Choate (played by Frances Bay) – The old woman at Schnitzer's bakery who bought the infamous last marble rye, which Jerry went on to steal from her on the street in order to give to George to carry out one of his numerous idiotic schemes. She reappeared in a later episode at Phase Two of the Pines of Mar Gables to cast the deciding vote in Morty's impeachment, when she recognized Jerry as the thief of her rye. She also appears in the final episode of the series as a witness testifying against Jerry, again bringing up the marble rye.
Marcelino (played by Miguel Sandoval) – The owner of the bodega on Jerry's block. In Season 8 "The Little Jerry", he runs an illegal cockfighting ring in the back of his store. In "The Millennium", Kramer mentions that Marcelino is 1/64 Mayan. Marcelino also appears in "The Finale" where he testifies about the cockfighting ring where he only quoted "cockfighting".
Marla Penny aka "The Virgin" (played by Jane Leeves) – A professional closet organizer whom Jerry dates. She eventually loses her virginity to John F. Kennedy Jr. She appears in "The Virgin", "The Contest", Part Two of "The Pilot" and "The Finale".
Matthew (played by John Christian Graas) – Son of the purveyor of the "fat-free" yogurt, Matthew is a 10-year-old boy who idolizes Jerry. In "The Non-Fat Yogurt" he overhears Jerry swearing, and, following his idol's lead, refers to Jerry as a "funny fucker". He ruins an audiocassette of Jerry's comedy. When the yogurt is revealed to have fat, Matthew cusses out Jerry. Matthew first appears in "The Parking Space" in season 3 and puts in his two cents over whether George has a parking space.
Mel Sanger (played by Brian Doyle-Murray) – A Yoo-Hoo truck driver who is the father of Donald Sanger. Mel appears to be very loving, but is frustrated about several things, including when people believe the bubble is like an igloo and the fact that his son Donald has the TV remote constantly. He appeared in "The Bubble Boy", "The Pilot" Pt. 2, and "The Finale" Pt. 2.
Mike Moffit (played by Lee Arenberg) – Calls Jerry a "phony" behind his back and gets into an argument with George over a parking space in front of Jerry's apartment ("The Parking Space"). He also appears as Kramer's bookie in "The Susie", in which Jerry accidentally breaks his thumbs and traps him in the trunk of Jerry's car.
Mr. Kruger (played by Daniel von Bargen) – President of Kruger Industrial Smoothing, for which George Costanza works during most of the ninth and final season. Kruger is noted for his total apathy towards his job and the success of his company. George's description of the company is "Kruger Industrial Smoothing: 'We don't care, and it shows'" ("The Strike"). George is often forced to push Kruger to do his work, to which Kruger usually responds, "I'm not too worried about it." He also attends the Festivus dinner. Kruger's company "botched the Statue of Liberty" job as they "couldn't get the green stuff off" and is infamous for losing money (when viewing the company financial reports Kruger nonchalantly exclaimed, "wow, we really took it on the chin last year"). Kruger appears in four episodes: "The Slicer", "The Strike", "The Burning" and "The Maid".
Mr. Morgan (played by Tom Wright) – A co-worker of George's at Yankee Stadium. He appears in four episodes, "The Pledge Drive", where George convinces Mr. Morgan that the Yankees should send a player to a PBS fundraiser after he sees George eating a candy bar with a knife and fork; "The Diplomat's Club", where he hints that George had a racial bias after George said that he looked like Sugar Ray Leonard; "The Mom and Pop Store", where George calls a meeting to convince the Yankees to have a "Jon Voight Day", and Mr. Morgan proposes they have no more meetings called by George; and "The Wink", where George causes a dispute with Mr. Morgan, his wife, and Mr. Steinbrenner by winking involuntarily, ultimately leading to Mr. Morgan's termination, and George being promoted to his position. Despite their adverse relationship in earlier episodes, in "The Wink" he tells George that he is his only friend at the Yankees office.
Mr. Tomasulo (played by Gordon Jump) – George's boss at "Play Now" in episodes 1 and 2 of Season 9, "The Butter Shave" and "The Voice".
Mrs. Landis (played by Gail Strickland) – A boss at Doubleday. She appeared twice in Season Six, in the episodes "The Chaperone" and "The Switch". She interviews Elaine for a job but thinks that she does not have enough grace.
