List of The Sarah Jane Adventures serials

The Sarah Jane Adventures is a British science fiction television programme that was produced by BBC Cymru Wales for CBBC. Created by Russell T Davies, it is a spin-off of the long-running science fiction programme Doctor Who. 53 episodes and 1 short were produced between 2006 and 2011 across five series. In comparison to Doctor Who's family-orientated viewership, The Sarah Jane Adventures is aimed at a younger audience generally aged between 6–12 years old.

The programme focuses on Sarah Jane Smith (Elisabeth Sladen), an investigative journalist and former companion to the Doctor, an alien time traveller whom Smith had numerous adventures with in her youth. Now living in modern-day Ealing, London, she investigates extraterrestrial matters and protects Earth against alien threats with a group of teenage accomplices: adopted son Luke Smith, neighbour Maria Jackson and friend Clyde Langer. New neighbour Rani Chandra and adopted daughter Sky Smith later join the cast. Additionally, the group is aided by Mr Smith, a sentient extraterrestrial computer, and K9, a dog-shaped robot gifted to Sarah Jane by the Doctor.

Following a New Year's Day special, the first series premiered on 24 September 2007, comprising 10 episodes (5 two-part serials). Series 2–4, each made up of 12 episodes (6 serials), respectively followed between 2008 and 2010. A fifth series of 12 episodes was commissioned in 2010, however, only 6 (3 serials) were completed before Sladen's death. They were posthumously broadcast in 2011.

For Series 1 and 2, after an episode was broadcast on BBC One, the next would air immediately after on CBBC. Certain repeats are broadcast in omnibus rather than the traditional Part One and Two format.[1]
