Soyuz 28 (Russian: Союз 28, Union 28) was a March 1978 Soviet crewed mission to the orbiting Salyut 6 space station.

Cosmonaut Vladimír Remek from Czechoslovakia became the first person launched into space who was not a citizen of the United States or the Soviet Union.

The flight was the first mission in the Intercosmos program that gave Eastern Bloc and other communist states access to space through crewed and uncrewed launches.

[3]: 182 Vladimir Remek, the first non-Soviet, non-American to travel to space, was launched aboard Soyuz 28 on 2 March 1978, after a three-day delay of unspecified cause.

The crew docked with the orbiting Salyut 6 space station, and greeted the occupants Georgi Grechko and Yuri Romanenko who had arrived on Soyuz 26 in December.
