Gordon Cooper
Also known as L. Gordon Cooper, Leroy Gordon Cooper, Gordo Cooper, Cooper
- Colonel, U.S. Air Force; Mercury Seven astronaut (Mercury-Atlas 9, 1963; Gemini 5, 1965); test pilot at Edwards AFB

Gordon Cooper (1927–2004) was a U.S. Air Force pilot and one of the seven original Mercury astronauts. After four years flying F-84s and F-86s from Neubiberg Air Base in West Germany, he graduated from the test pilot school at Edwards Air Force Base in 1956 and served there as a test pilot and project manager in Flight Test Engineering. In 1963 he flew Faith 7 (Mercury-Atlas 9), the last and longest Mercury mission, finishing it under manual control after equipment failures, and in 1965 he commanded Gemini 5, an eight-day endurance record.
From the late 1970s Cooper said publicly that he had seen UFOs over West Germany in 1951, and that in 1957 a camera crew he had sent out at Edwards filmed a saucer landing, film he sent to the Pentagon. The crew's own account, given to the physicist James McDonald and later researchers, is of a disc photographed in flight, with no landing and no role for Cooper. Asked about the case in 1978, he said he had seen nothing personally and it was “all second hand evidence”. He addressed a United Nations committee in March 1978 and called for a coordinated scientific program in a letter for its November 1978 discussion of UFOs, and told his story again in his memoir Leap of Faith (2000) and the documentary Out of the Blue (2003). He died in Ventura, California, in October 2004.
