Stephen Gerard Bowen (born February 13, 1964) is a United States Navy submariner and a NASA astronaut; he was the second submariner to travel into space. Bowen has been on three spaceflights, all of which were Space Shuttle missions to the International Space Station. His first mission, STS-126, took place in November 2008, and his second was STS-132 in May 2010.

In March 2011, Bowen completed his third spaceflight as a Mission Specialist on STS-133, which was Space Shuttle Discovery's final planned flight. Having flown on both STS-132 and STS-133, Bowen became the first and only astronaut to fly on consecutive shuttle missions. Originally Tim Kopra was scheduled to fly on STS-133, but Kopra had a bicycle injury shortly before the mission, and so he was replaced by Bowen.

Upon completion of the submarine training pipeline, Bowen spent three years attached to USS Parche and completed qualification in submarines on USS Pogy. After attending the MIT/WHOI Joint Program in Ocean Engineering he reported to USS Augusta for duty as the Engineering Officer. During this tour he qualified for command of nuclear powered submarines. In 1997, he reported to the United States Special Operations Command (USSOCOM) in the Office of Plans and Policy and worked on the USSOCOM Future Concepts Working Group. For nine months in 1999 he was the Reactor and Propulsion inspector for the Navy's Submarine Board of Inspection and Survey (INSURV). In May 2000 he became the first Executive Officer of the Pre-Commissioning Unit Virginia, the first of the new Virginia-class submarines.
