Death Valley (Panamint: Tümpisa [tɨmbiʃa]) is a desert valley in Eastern California, United States, in the northern Mojave Desert, bordering the Great Basin Desert. The World Meteorological Organization lists Death Valley as the site of the hottest surface temperature recorded on Earth.

On the afternoon hours of July 10, 1913, the United States Weather Bureau recorded a temperature of 134 °F (56.7 °C) at Furnace Creek in Death Valley, which stands as the highest ambient air temperature ever recorded on the surface of the Earth. However, this reading and several others taken in that period are disputed by some modern experts due to observer issues and regional disparities in temperature values. The highest reliable temperature in Death Valley is 130 °F (54.4 °C) recorded at Furnace Creek on August 16 2020 and July 9 2021. This is still the highest reliable temperature recorded globally.

Lying mostly in Inyo County, California, near the border of California and Nevada, in the Great Basin, east of the Sierra Nevada mountains, Death Valley constitutes much of Death Valley National Park and is the principal feature of the Mojave and Colorado Deserts Biosphere Reserve. It runs from north to south between the Amargosa Range on the east and the Panamint Range on the west. The Grapevine Mountains and the Owlshead Mountains form its northern and southern boundaries, respectively. It has an area of about 3,000 sq mi (7,800 km2). The highest point in Death Valley National Park is Telescope Peak, in the Panamint Range, which has an elevation of 11,043 feet (3,366 m).

Death Valley is home to the Timbisha tribe of Native Americans, formerly known as the Panamint Shoshone. They have inhabited the valley for at least the past millennium. Their name for Death Valley is Tümpisa, meaning "rock paint". This refers to the presence of red ochre in the valley.

The valley got the name Death Valley in the winter of 1849–1850 when a group of American pioneers were traveling through on their way to the California gold rush. The Death Valley 49ers got lost in the valley and feared that they would all perish there. They did eventually make their way out after suffering the loss of just one of the group.
