This is an alphabetical list of astronauts, people selected to train for a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft.

For a list of everyone who has flown in space, see List of space travelers by name.

More than 600 people have been trained as astronauts. Until recently, astronauts were sponsored and trained exclusively by governments, either by the military or by civilian space agencies. However, with the advent of suborbital flight starting with 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 trains for travel into space—including scientists, politicians, journalists, and tourists—this article lists only professional astronauts, those who have been selected to train professionally. This includes national space programs, industry and commercial space programs which train and/or hire their own professional astronauts.

The flags indicate the astronaut's primary citizenship during his or her time as an astronaut. The symbol identifies female astronauts. The symbol △ indicates astronauts who have left low Earth orbit. The symbol ▲ indicates astronauts who have walked on the Moon. The symbol † indicates astronauts who have died in incidents related to a space program.
