The 726th Fighter Aviation Regiment (Russian: 726-й истребительный авиационный полк; 726th IAP) was an aviation regiment of the Soviet Air Forces and the Soviet Air Defense Forces. Formed in 1949, the regiment was equipped with the Mikoyan-Gurevich MiG-15 for most of its service. It served at Yaroslavl as an air defense interceptor unit before being sent to northeast China to serve as part of the 64th Fighter Aviation Corps, the Soviet air unit in the Korean War. Flying from airfields in northeast China, the 726th fought in combat for a year, from July 1952 to July 1953, notably against United States Air Force F-86 Sabres in MiG Alley. After the end of hostilities in the Korean War, the regiment returned to Yaroslavl, where it was disbanded in 1958.
