LK-1 was a projected Soviet crewed lunar flyby spacecraft. It would be launched on a three-stage Proton launch vehicle. The project started in 1962 under the lead engineer Vladimir Chelomey,{{Cite web|url=https://fas.org/spp/eprint/lindroos_moon1.htm|title=The Soviet Manned Lunar Program}} with the first flight planned for 1967.
The LK-1 had its origin in several early 1960s spacecraft projects under the generic names of kosmoplans and raketoplans.{{Cite web|url=http://www.astronautix.com/craft/lk1.htm|archive-url=https://web.archive.org/web/20011225105321/http://www.astronautix.com/craft/lk1.htm|url-status=dead|archive-date=December 25, 2001|title = LK-1}}
In 1965 the project was cancelled in favour of the Soyuz 7K-L1 spacecraft.
Further developments came as the LK-700 direct-descent lunar lander program.
