List of episodes (1963–1989)

Logopolis is the seventh and final serial of the 18th season of the British science fiction television series Doctor Who, which was first broadcast in four weekly parts on BBC1 from 28 February to 21 March 1981. It was Tom Baker's last story as the Fourth Doctor and marks the first appearance of Peter Davison as the Fifth Doctor and Janet Fielding as new companion Tegan Jovanka.

The serial is set on the planets Earth and Logopolis. In the serial, the Doctor, a time traveller from the planet Gallifrey, forms a temporary truce with his arch-enemy the Master (Anthony Ainley) to stop the unravelling of the universe which the Master had started by accident.

The serial was the last Doctor Who story aired on Saturday evening for four years. When Peter Davison took over as the Fifth Doctor in January of 1982, the BBC moved Doctor Who from Saturday nights to a new weekday prime time slot, airing two episodes per week; it did not return to Saturday evenings until 1985.
