Class is a British science fiction drama programme and a spin-off of the long-running programme Doctor Who. It was created and written by Patrick Ness, who also produced alongside Doctor Who showrunner and lead writer Steven Moffat, and Brian Minchin, who acted as producer on Doctor Who and two of its previous spin-offs, Torchwood and The Sarah Jane Adventures.

The series of eight episodes was released on BBC Three between 22 October and 3 December 2016. The story focuses on five of the students and staff at Coal Hill Academy, a longtime recurrent location of Doctor Who, who are tasked by the Doctor to deal with alien threats while trying to deal with their personal lives.

The series received generally positive reviews from critics, with praise for its darker tone, writing, themes, characters, and acting. However, the series scored poor viewership figures for its broadcast on BBC One. In September 2017, BBC Three confirmed that the series was cancelled.

In 2018 Big Finish Productions produced a series of six Class audio adventures, telling the further adventures of the students at Coal Hill Academy. Six more audio adventures were announced for release starting in April 2020, with two of the main characters being recast.
