Thomas Kenneth Mattingly II (born March 17, 1936), (RADM, USN, Ret.), better known as Ken Mattingly, is a former American naval officer and aviator, aeronautical engineer, test pilot, Rear Admiral in the United States Navy and astronaut who flew on the Apollo 16, STS-4 and STS-51-C missions.

Mattingly had been scheduled to fly on Apollo 13, but three days prior to launch, he was held back and removed from the mission due to exposure to German measles (which he did not contract).

He later flew as Command Module Pilot for Apollo 16 and made 64 lunar orbits, making him one of 24 people to have flown to the Moon. Mattingly and his commander from Apollo 16, John Young, are the only persons to have flown to the Moon and also a Space Shuttle orbital mission (Fred Haise, his former training crewmate from Apollo 13, did atmospheric flight testing of the Space Shuttle "Approach and Landing Tests").
