The 15th Test Squadron is an inactive United States Air Force unit. Its last assignment was with the Air Force Materiel Command at Hill Air Force Base, Utah, where it was inactivated.

The squadron was activated as the 15th Pursuit Squadron in early 1941 as part of the Southeast Air District. It was equipped with a series of pursuit aircraft with a mission of air defense of Florida. After the Pearl Harbor Attack, the squadron was assigned to the Caribbean Air Force in Panama where it operated in defense of the Panama Canal. It returned to the United States in early 1943 where it became a Republic P-47 Thunderbolt (later North American P-51 Mustang) replacement training unit (RTU) for III Fighter Command. It was disbanded on 1 May 1944 as part of a reorganization of training units.

The squadron was reactivated in 1953 as the 15th Fighter-Interceptor Squadron, part of Air Defense Command. It was equipped with North American F-86A Sabre day fighters at Davis-Monthan Air Force Base, Arizona with a mission of air defense of the Southwest United States. It Re-equipped in 1954 with North American F-86D Sabres. In 1957 it began re-equipping with the F-86L, an improved version of the F-86D which incorporated the Semi Automatic Ground Environment, or SAGE computer-controlled direction system for intercepts. The service of the F-86L destined to be quite brief, since by the time the last F-86L conversion was delivered, the type was already being phased out in favor of supersonic interceptors.
