Terror of the Autons is the first serial of the eighth season of the British science fiction television series Doctor Who. It was broadcast in four weekly parts on BBC1 from 2 to 23 January 1971.

The serial is set in various locations in England. In the serial, the alien time traveller the Third Doctor and the organisation UNIT work to stop the Master, a renegade Time Lord just like the Doctor, from using a radio telescope to summon an invasion force of the incorporeal intelligence the Nestenes to Earth. The serial introduced three new characters: the Doctor's new companion, Jo Grant; his archenemy the Master; and Captain Mike Yates.
