The criteria for determining who has achieved human spaceflight vary. The Fédération Aéronautique Internationale (FAI) defines spaceflight as any flight over 100 kilometres (62 mi), while in the United States, professional, military and commercial astronauts who travel above an altitude of 50 miles (80 km) are awarded astronaut wings. The majority of people who have flown into space have done so by entering Earth orbit. This list includes people meeting all three criteria, in separate subdivisions.

Countries (and successor states) whose citizens have flown in space as of January 2024.

The flags indicate the space traveler's nationality at the time of their flight. In cases of dual citizenship, the space traveler is listed under their primary residence. A secondary list appended to the entry for the Soviet Union shows the birth countries of space travelers not born in Russia. A similar list after the entry for the United States shows the birth countries of space travelers who were citizens of the US but were born elsewhere. Flags shown in the secondary lists are those in use at the time of the space travelers' birth.

Names in italic are space travelers who are not part of any national astronaut program or astronaut corps (Toyohiro Akiyama, Helen Sharman, the Space Adventures customers and the sub-orbital SpaceShipOne and Blue Origin pilots).
