The Invasion is the partly missing third serial of the sixth season of the British science fiction television series Doctor Who, which was first broadcast in eight weekly parts from 2 November to 21 December 1968.

In the serial, the megalomaniac Tobias Vaughn (Kevin Stoney), the head of the hugely successful electronics company International Electromatics, forms an alliance with the Cybermen to take control of Earth.

The Invasion marks the first appearance of UNIT, the second appearance of Lethbridge-Stewart (Nicholas Courtney), now promoted to Brigadier, and introduces Corporal Benton (John Levene), later to become a sergeant during the Third Doctor's era. It was the first incomplete Doctor Who serial to be released on DVD with full-length animated reconstructions of its two missing episodes.
