The Android Invasion is the fourth serial of the thirteenth season of the British science fiction television series Doctor Who, which was first broadcast in four weekly parts on BBC1 from 22 November to 13 December 1975.

The serial is set on the planet Oseidon and in England. In the serial, the alien race the Kraals plot to wipe out humanity with a virus to prepare the Earth for their invasion.

The serial was directed by former series producer Barry Letts and written by Terry Nation — his first Doctor Who script for eleven years not to feature his creations, the Daleks. The serial marks the last appearances in the programme of both John Levene in his recurring role as Sergeant Benton, and also of Ian Marter, who makes a guest appearance as previous companion Harry Sullivan.
