The Middle East is a geo-political region that is generally defined as encompassing all of Egypt and all of West Asia except for the Caucasus. It roughly corresponds with what was historically referred to in Western Europe as the Near East, which was juxtaposed with the Far East. Unlike West Asia's adherence to continental boundaries, the Middle East is demarcated by following political borders and consequently includes East Thrace in Southeast Europe because it is a part of Turkey. Since the early 20th century, the term "Middle East" has grown increasingly prominent in international discourse, although it is often prone to causing confusion or disagreement on account of vague and changing definitions of what countries and regions it spans. The related terms "Middle East and North Africa" and "Greater Middle East" denote other existing concepts of the region that involve extending the "Middle East" to incorporate most Muslim-majority countries.

Today, the bulk of Middle Eastern countries (13 out of 18) are part of the Arab world. The three most populous Middle Eastern countries are Egypt, Iran, and Turkey, while Saudi Arabia is the largest Middle Eastern country by area. Arabs are the most widespread ethnic group in the region, followed by Turks, Persians, Kurds, Jews, and Assyrians. Significant geographical features or regions that constitute the Middle East are the Arabian Peninsula, Anatolia, the Levant and Mesopotamia (together comprising the Fertile Crescent), and the Iranian plateau.

The history of the Middle East is among the richest ever recorded, as it was the first region to be settled by modern humans outside of Africa and the first region in which writing systems were developed. Situated at the intersection of Africa, Europe, and Asia, the Middle East was home to several cradles of civilization and has been recognized by both local and foreign populations as a region of great strategic importance for millennia. All of the core Abrahamic religions (Judaism, Christianity, and Islam) originated and have their holiest sites in the Middle East.
