The twelfth series of the British science fiction television programme Doctor Who premiered on 1 January 2020 and aired until 1 March 2020. It is the second series to be led by Chris Chibnall as head writer and executive producer, alongside executive producer Matt Strevens, the twelfth to air after the programme's revival in 2005, and the thirty-eighth season overall. The twelfth series was broadcast on Sundays, except for the premiere episode, continuing the trend from the eleventh series. Prior to the eleventh series, regular episodes of the revived era were commonly broadcast on Saturdays. The series was followed by the 2021 New Year's Day special, "Revolution of the Daleks".
