'''Interkosmos''' ({{langx|ru|Интеркосмос}}) was the first international and multi-national [[Soviet space program]], designed to help the Soviet Union's allies and countries from the [[Non-Aligned Movement]] with [[Human spaceflight|crewed]] and [[Uncrewed spacecraft|uncrewed]] space missions.

The program was formed in April 1967 in [[Moscow]].<ref>{{Cite book|last1=Bergess|first1=Colin|url=https://books.google.com/books?id=MG__CgAAQBAJ|title=Interkosmos - The Eastern Bloc's Early Space Program|last2=Vis|first2=Bert|publisher=Springer Praxis|year=2015|isbn=978-3-319-24161-6|location=[[New York City|New York]]|pages=11|doi=10.1007/978-3-319-24163-0|lccn=2015953234}}</ref><ref>{{Cite web|last=Matignon|first=Louis de Gouyon|date=2019-04-05|title=The Interkosmos space program|url=https://www.spacelegalissues.com/space-law-interkosmos/|access-date=2021-06-08|website=Space Legal Issues|language=en-US|archive-date=2020-06-22|archive-url=https://web.archive.org/web/20200622183340/https://www.spacelegalissues.com/space-law-interkosmos/|url-status=dead}}</ref> All members of the program from USSR were given the [[Hero of the Soviet Union]] medal or the [[Order of Lenin]]. The program included the allied east-European states of the [[Warsaw Pact]], [[Eastern Bloc]], [[Council for Mutual Economic Assistance|CoMEcon]], and other socialist states like [[Democratic Republic of Afghanistan|Afghanistan]], Cuba, [[Mongolian People's Republic|Mongolia]], and Vietnam. [[Non-Aligned Movement|Non-aligned]] states such as India and Syria participated,<ref>{{Cite news|date=1984-04-04|title=INDIAN JOINS SOVIET PAIR IN 8-DAY SPACE MISSION|language=en-US|work=The New York Times|url=https://www.nytimes.com/1984/04/04/us/indian-joins-soviet-pair-in-8-day-space-mission.html|access-date=2021-06-08|issn=0362-4331}}</ref><ref>{{Cite web|last=Garthwaite|first=Rosie|date=2016-03-01|title=From astronaut to refugee: how the Syrian spaceman fell to Earth|url=http://www.theguardian.com/world/2016/mar/01/from-astronaut-to-refugee-how-the-syrian-spaceman-fell-to-earth|access-date=2021-06-08|website=the Guardian|language=en}}</ref> and capitalist states such as the United Kingdom, France and Austria.<ref name="Sheehan">{{cite book|last=Sheehan|first=Michael|title=The international politics of space|year=2007|publisher=Routledge|isbn=978-0-415-39917-3|url=https://books.google.com/books?id=V-Z0kfqPHy8C|location=London|pages=59–61}}</ref><ref name="Burgess">{{cite book|last1=Burgess|first1=Colin |last2=Hall|first2=Rex |title=The first Soviet cosmonaut team: their lives, legacy, and historical impact|year=2008|publisher=Springer|isbn=978-0-387-84823-5|url=https://books.google.com/books?id=rrdVPtCNL9AC|location=Berlin|page=331}}</ref>

Following the [[Apollo–Soyuz]] mission, there were talks between [[NASA]] and Interkosmos in the 1970s about a "Shuttle–Salyut" program to fly [[Space Shuttle]] missions to a Salyut space station, with later talks in the 1980s even considering flights of the future [[Buran-class orbiter|''Buran''-class orbiter]] to a future US space station.<ref name=MIRheritage>[[Wikisource:Mir Hardware Heritage/Part 2 - Almaz, Salyut, and Mir#2.1.6 Shuttle-Salyut .281973-1978.3B 1980s.29]].</ref>
Whilst the Shuttle–Salyut program never materialized during the existence of the Soviet Interkosmos program, after the [[dissolution of the Soviet Union]] the [[Shuttle–Mir program]] would follow in these footsteps in the mid-1990s and eventually pave the way to the [[International Space Station]].

Beginning in April 1967 with unpiloted research [[satellite]] missions, the first crewed Interkosmos mission occurred in February 1978.<ref name=Burgess /> Joint crewed spaceflights enabled 14 non-Soviet [[cosmonaut]]s to participate in [[Soyuz (spacecraft)|Soyuz]] space flights between 1978 and 1988. The program was responsible for sending into space the first citizen of a country other than the US or USSR: [[Vladimír Remek]] of [[Czechoslovak Socialist Republic|Czechoslovakia]].<ref name=Sheehan /> Interkosmos also resulted in the first black and Hispanic person in space, [[Arnaldo Tamayo Méndez]] of Cuba, and the first Asian person in space, [[Phạm Tuân]] of Vietnam. Of the countries involved, only [[Bulgarian cosmonaut program|Bulgaria sent two cosmonauts]] to space, although the second one did not fly under the Interkosmos program, and the French spationaut [[Jean-Loup Chrétien]] flew on two flights.<ref>{{Cite news|last=Pinkham|first=Sophie|date=2019-07-16|title=How the Soviets Won the Space Race for Equality|language=en-US|work=The New York Times|url=https://www.nytimes.com/2019/07/16/us/how-the-soviets-won-the-space-race-for-equality.html|access-date=2021-06-08|issn=0362-4331}}</ref>

The Soviet Union also made offers of joint human spaceflight on a commercial basis to the United Kingdom and Japan, resulting in the first British and Japanese cosmonauts. In the early 1980s, an offer was made to Finland as well, with test pilot [[:fi:Jyrki Laukkanen|Jyrki Laukkanen]] mentioned as one of the potential Finnish cosmonauts. The pilots of the Test Flight ({{lang|fi|Koelentue}}) refused on the grounds that participation would not benefit the flight or test pilot activity in any way. No further offers were made to Finland.<ref>{{cite web|language = fi | url = https://yle.fi/uutiset/3-10869586 | title = Jyrki Laukkasesta piti tulla Suomen ensimmäinen kosmonautti – kieltäytyi kutsusta, kun siitä ei olisi ollut mitään hyötyä | date = 10 July 2019 | publisher = Yle.fi | access-date = July 26, 2020 }}</ref><ref>{{cite web|language = fi | url = https://www.suomentietokirjailijat.fi/kirjailijalle/tutustu-tietokirjailijaan/jyrki-laukkanen.html | publisher = Suomen Tietokirjailijat ry | title = Jyrki Laukkanen | access-date = July 26, 2020 }}</ref>
