The Moonbase is the half-missing sixth serial of the fourth season in the British science fiction television series Doctor Who, which was first broadcast on BBC1 in four weekly parts from 11 February to 4 March 1967.

In this serial, the Second Doctor (Patrick Troughton) and his travelling companions Ben (Michael Craze), Polly (Anneke Wills) and Jamie McCrimmon (Frazer Hines) arrive on the Human colonised Moon in 2070, where the Cybermen plot to take over the base and use it to invade the Earth. This story features the return, and first redesign, of the Cybermen, after their popularity in The Tenth Planet earlier in the season.

The serial showed an improvement in ratings for Doctor Who, with an average of 8.3 million viewers. The serial has received mixed to positive reviews from critics, with most preferring the Cybermen's first outing. Still, The Moonbase was popular enough for a third Cybermen story to be commissioned. In 2014, The Moonbase was the fifth incomplete Doctor Who serial to be released with full-length animated reconstructions of its two missing episodes.
