List of astronauts by name

This is an alphabetical list of astronauts, people trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft. Until recently, astronauts were sponsored and trained exclusively by governments, either by the military or by civilian space agencies. However, with the first sub-orbital flight of the privately-funded SpaceShipOne in 2004, a new category of astronaut was created - the commercial astronaut.

While the term astronaut is sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists, this article only lists professional astronauts. A list of everyone who has flown in space can be found at List of space travelers by name.

Names in "italic" are astronauts who have left Low Earth orbit, names in bold are astronauts who have .

The flags indicate citizenship during time as an astronuat. As of 2008, more than 480 people had trained as astronauts.
