Al Udeid Air Base (Arabic: قاعدة العديد الجوية) is one of two military bases southwest of Doha, Qatar, also known as Abu Nakhlah Airport (مطار أبو نخلة).

It houses the Qatar Emiri Air Force, United States Air Force, Royal Air Force, and other foreign forces. It is host to a forward headquarters of United States Central Command, headquarters of the United States Air Forces Central Command, No. 83 Expeditionary Air Group RAF, and the 379th Air Expeditionary Wing of the USAF.

In 1999, the then Emir of Qatar, Sheikh Hamad, told U.S. officials that he would like to see as many as 10,000 U.S. servicemen permanently stationed at Al Udeid. According to media reports in June 2017, the base hosted over 11,000 U.S. and U.S.-led anti-ISIL coalition forces and over 100 operational aircraft.

It is the largest U.S. military base in the Middle East.
