The Caves of Androzani is the sixth serial of the 21st season of the British science fiction television series Doctor Who, which was first broadcast in four twice-weekly parts on BBC1 from 8 to 16 March 1984.

In the serial, the Doctor becomes involved in a war for control of the life-prolonging substance "spectrox" on the planet Androzani Minor, which is being fought between the ruthless businessman Morgus (John Normington) and the android-builder Sharaz Jek (Christopher Gable).

The Caves of Androzani was Peter Davison's last regular appearance as the Fifth Doctor, marked the first appearance of Colin Baker as the Sixth Doctor, and saw the return of scriptwriter Robert Holmes to the series for the first time since 1978. It was also Graeme Harper's first work on the series as a full director, having worked on earlier serials as an assistant director. In 2009, The Caves of Androzani was voted by fans as the best Doctor Who story in history.
