Planet of Evil is the second serial of the 13th season of the British science fiction television series Doctor Who. It was first broadcast in four weekly parts on BBC1 from 27 September to 18 October 1975.

The serial is set on and above the planet Zeta Minor, the last undiscovered planet in the known universe, more than 30,000 years in the future, where the Morestran geologist Sorenson (Frederick Jaeger) seeks to exploit the antimatter minerals on the planet to use as a power source for his own planet. He and the military mission looking for him are attacked by a creature from a universe of anti-matter. The Fourth Doctor and Sarah Jane Smith arrive on the planet in response to a distress call. They find the geological expedition attacked by an unseen killer, leaving only Professor Sorenson alive.

The plot was inspired by the film Forbidden Planet (1956) and the novella Strange Case of Dr Jekyll and Mr Hyde (1886), with a focus on antimatter. The jungle setting was realised at Ealing Studios and shot on film.
