Patrick Pierre Roger Baudry (born March 6, 1946, in Cameroon) is a retired lieutenant colonel in the French Air Force and a former CNES astronaut.

He was a member of the back-up crew for the French-Soviet Soyuz T-6 Intercosmos mission and was trained for scientific experiments in the fields of physiology, biology, materials processing in space, and astronomy.

STS-51-G was launched from Kennedy Space Center, Florida, and returned to land at Edwards Air Force Base, California.

The international crew aboard Discovery deployed communications satellites for Mexico (Morelos), the Arab League (Arabsat), and the United States (AT&T Telstar).

They deployed and later retrieved the SPARTAN satellite, which performed 17 hours of x-ray astronomy experiments while separated from the Space Shuttle.
