The Chase is the eighth serial of the second season in the British science fiction television series Doctor Who. Written by Terry Nation and directed by Richard Martin, the serial was broadcast on BBC in six weekly parts from 22 May to 26 June 1965. Set in multiple time periods on several different planets, including Aridius, Earth, and Mechanus, the serial features the Dalek race travelling through time while pursuing the TARDIS and its occupants—the First Doctor and his companions Ian Chesterton, Barbara Wright, and Vicki —to kill them and seize the TARDIS for themselves. The Doctor and companions encounter several characters, including monsters Dracula and Frankenstein's monster, human astronaut Steven Taylor, and an android replica of the Doctor.

The second season of British science fiction television series Doctor Who was originally broadcast on BBC1 between 1964 and 1965. The season began on 31 October 1964 with Planet of Giants and ended with The Time Meddler on 24 July 1965. Like the first season, production was overseen by the BBC's first female producer Verity Lambert. Story editor David Whitaker continued to handle the scripts and stories during early production, handing over to Dennis Spooner as the season began to air; Spooner subsequently left his role by the season's end, and was replaced by Donald Tosh for its final serial. By the season's end, Lambert was the only remaining production member from the team responsible for creating the series.
