The Turkish Air Force (Turkish: Türk Hava Kuvvetleri) is the aerial warfare service branch of the Turkish Armed Forces. It ranks 2nd in NATO in terms of fleet size behind the USAF with a current inventory of 1.944 aircraft.

The history of Ottoman military aviation dates back to between June 1909 and July 1911. The Ottoman flight squadrons participated in the Balkan Wars (1912–1913) and World War I (1914–1918). The fleet size reached its apex in December 1916, when the Ottoman aviation had 90 active combat aircraft. The General Inspectorate of Air Forces (Kuva-yı Havaiye Müfettiş-i Umumiliği) trying to reconstruct itself on July 29, 1918 had no personnel, but only remained as a title on paper.

After the end of World War I and the occupation of the Ottoman Empire by the Allies in 1919, some Turkish aviators tried to build new units in Istanbul, İzmir, Konya, Elazığ and Diyarbakır with planes left over from World War I and tried to bring together flight personnel. During the Turkish War of Independence, Turkish pilots joined the Konya Air Station (Konya Hava İstasyonu). With the formation of the Grand National Assembly (GNA) by Mustafa Kemal and his colleagues on April 23, 1920, in Ankara, and the reorganization of the army, the Branch of Air Forces (Kuva-yı Havaiye Şubesi) was established under the Office of War (Harbiye Dairesi) of the GNA. A few damaged aircraft belonging to the GNA were repaired, and afterwards used in combat.

An air force, also known in some countries as an air army, is in the broadest sense, the national military organization that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army, navy or other branch. Typically, air forces are responsible for gaining control of the air, carrying out strategic and tactical bombing missions and providing support to surface forces.

The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation within a national air force. Air forces typically consist of a combination of fighters, bombers, helicopters, transport planes and other aircraft.

Many air forces are also responsible for operations of military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air defence assets such as antiaircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems. Some nations, principally Russia, the former Soviet Union and countries who modelled their militaries along Soviet lines, have an Air Defence Force which is organizationally separate from their air force.
