The tenth season of British science fiction television series Doctor Who began on 30 December 1972 with the tenth anniversary special The Three Doctors, and ended with Katy Manning's final serial The Green Death. This is the Third Doctor's (played by Jon Pertwee) fourth series, as well as fourth for producer Barry Letts and script editor Terrance Dicks.

Jon Pertwee continues his role as the Third Doctor, and Jo Grant played by Katy Manning makes her final regular appearance in The Green Death.
Nicholas Courtney, John Levene and Richard Franklin continue their recurring roles of UNIT personnel Brigadier Lethbridge-Stewart, Sergeant Benton and Captain Mike Yates respectively.
Previous lead actors William Hartnell and Patrick Troughton return to guest as the First and Second Doctors in the programme's tenth anniversary serial, The Three Doctors, although illness limited Hartnell's involvement. This was the first time that previous incarnations of the Doctor had returned to the programme, in what would become a regular feature of anniversary episodes.
Roger Delgado makes his final appearance as The Master in Frontier in Space. He died in a car crash in Turkey shortly after the story's transmission.[1]

At the conclusion of The Three Doctors, the Doctor is finally released from his sentence of exile by the Time Lords, enabling him to travel through time and space once again. This ends the cycle of mostly Earth-bound stories where the Doctor was stranded that began at the conclusion of The War Games in 1969.
The serials Frontier in Space and Planet of the Daleks both feature the Daleks and lead directly from the first into the second, forming a rough twelve-part epic.
The entire season was broadcast from 30 December 1972 to 23 June 1973.
