Downton Abbey made 52 episodes across six television series. The British period drama premiered on ITV in September 2010 and concluded with its sixth series in 2015, with the final episode broadcast on Christmas Day.
The total includes the regular episodes and the feature-length Christmas specials that formed part of the show's annual schedule. Those specials are sometimes counted differently by streaming services. Some platforms split a single Christmas special into two entries, which can make the programme appear to have 57 episodes instead of 52. The standard broadcast count, and the canonical answer for a trivia question about the series, remains 52.
Downton Abbey was created by Julian Fellowes and produced by Carnival Films for ITV in Britain and Masterpiece in the United States. Its six-series run follows the Crawley family and their servants from 1912 through the 1920s. The 2019 and later feature films are separate productions and are not included in the television episode total.
