Soyuz T-11 was the sixth expedition to the Soviet Salyut 7 space station, which in 1984 carried the first Indian cosmonaut along with Soviet crew members.

Salyut 7 was uncrewed after the undocking of Soyuz T-11 in October 1984 until Soyuz T-13 docked with the station in June 1985. Salyut 7 developed problems during the time it was uncrewed, which meant that the crew of Soyuz T-13 had to perform a manual docking and do repairs to the station.
