The Tenth Planet is the partly missing second serial of the fourth season in the British science fiction television series Doctor Who, which was first broadcast in four weekly parts from 8 to 29 October 1966. It was William Hartnell's last regular appearance as the First Doctor, and the first story to feature the Cybermen. Patrick Troughton also makes his first, uncredited appearance as the Second Doctor. Only three of the four episodes are held in the BBC archives; one remains missing although the regeneration sequence and various other scenes have been discovered intact. It is the fourth now-incomplete Doctor Who serial to be released with a full-length animated reconstruction of its missing episode.

The Doctor and his companions Ben and Polly arrive in the TARDIS at the South Pole in the year 1986, near the Snowcap base. The base is supervising the mission of the Zeus IV spaceship, running a routine probe on the Earth's atmosphere.

Unusual readings on the spaceship's instruments lead to the discovery of a new planet suddenly approaching Earth. The spaceship begins to experience power losses, and Snowcap personnel begin arrangements to abort its mission.

Back on the base, the Doctor reveals what he knows about the tenth planet: it is Mondas, Earth's former sister planet and its inhabitants will soon be visiting Earth. True to his prediction, three robotic creatures land outside, killing the guards and disguising themselves in the dead men's furs to gain access.
