LK-700 was a Soviet direct ascent lunar lander program proposed in 1964.{{cite web|url=http://www.astronautix.com/craft/lk700.htm|title=LK-700|work=astronautix.com|accessdate=5 July 2015|url-status=dead|archiveurl=https://web.archive.org/web/20131121214206/http://www.astronautix.com/craft/lk700.htm|archivedate=21 November 2013}} It was developed by Vladimir Chelomey as an alternative to the N1-L3 program. It was also a further development of the LK-1 lunar flyby spacecraft.

It would have been launched using the proposed UR-700{{Cite web|url=https://www.russianspaceweb.com/ur700.html|title = UR-700 launch vehicle}} rocket (related to the Proton rocket) with a crew of three cosmonauts on a direct flight to the lunar surface and back.

The direct landing approach would allow the Soviets to land anywhere on the moon's nearside.{{cite web|url=http://news.discovery.com/space/history-of-space/what-would-a-soviet-moon-landing-have-looked-like-130722.htm|title=What Would a Soviet Moon Landing Have Looked Like?|work=DNews|accessdate=5 July 2015|archive-date=3 May 2016|archive-url=https://web.archive.org/web/20160503002347/http://news.discovery.com/space/history-of-space/what-would-a-soviet-moon-landing-have-looked-like-130722.htm|url-status=dead}} The program was canceled in 1974.
