Season 3

This article is for the 1965-66 season of Doctor Who; for other third seasons of other programmes, see Series 3.

The third season of Doctor Who ran between 11 September 1965 and 16 July 1966. The season was marked by extremes. At twelve episodes, The Daleks' Master Plan was the longest story in the show's history until superceded by the fourteen-episode The Trial of a Time Lord in 1986 (although some consider that tale to be four separate serials broadcast under a single title); the single-episode story Mission to the Unknown remains the shortest Doctor Who story ever televised (not counting the several mini-episodes produced since 2005) and the only one in which neither the Doctor nor any companions appear (this designation, though, is controversial, as its role as a prologue to Daleks' Master Plan renders it more the thirteenth episode of that story rather than a standalone). The season also had the greatest number of different companions (seven), and producers (three). It also featured the first appearance of actor Nicholas Courtney, although not in his most famous role as The Brigadier. This was also the season of The War Machines, to date the only televised story in which the taboo of never referring to the Doctor directly by the name "Doctor Who" is broken.

Behind the scenes, it was dominated by the departure of Verity Lambert, the immensely exhausting production of The Daleks' Master Plan, and preparations for William Hartnell's departure – including intense discussion over how to handle such an unprecedented changed in a lead actor on a show still at the height of popularity. It consisted of ten serials (listed below) and forty-five episodes, the majority of which are considered lost, though three serials, The Ark, The Gunfighters and The War Machines, exist in complete form.
