List of space travelers by nationality. The criteria for determining who has achieved human spaceflight vary. The  (FAI) defines spaceflight as any flight over , while in the United States, professional, military and commercial astronauts who travel above an altitude of  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.

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).

Statistics 

, people from 47 countries have traveled in space. 644 people have reached the altitude of space according to the FAI definition of the boundary of space. 681 people have reached the altitude of space according to the USAF definition, and 610 have reached Earth orbit. 24 people have traveled beyond low Earth orbit and either circled, orbited, or walked on the Moon.

Of the 44 countries whose citizens have traveled into Earth's orbit, 25 have flown a single space traveler, and four others (Belgium, Bulgaria, the Netherlands, and the United Kingdom) have flown two each. 94% of all space travelers have hailed from the following eight nations:

1 Includes both national space programme activity and European Space Agency participation.
2 Includes astronauts from the Federal Republic of Germany and the German Democratic Republic.
