Who will portray "Doctor Who" in season 11 of the series premiering in 2018?

Jodie Whittaker portrayed the Doctor in season 11 of Doctor Who, which premiered in 2018.

Whittaker became the Thirteenth Doctor, succeeding Peter Capaldi after his final appearance in the 2017 Christmas special, “Twice Upon a Time.” Her first full episode, “The Woman Who Fell to Earth,” aired on October 7, 2018, beginning a new era for the long-running BBC science-fiction series.

Her casting was historically significant because she was the first woman to play the Doctor in the television series. The Doctor is a Time Lord who can regenerate into a new body, allowing the role to continue with a different actor while remaining the same character. This regeneration tradition began in 1966, when William Hartnell was replaced by Patrick Troughton.

Season 11 also introduced new companions Graham O’Brien, Ryan Sinclair, and Yasmin Khan, played by Bradley Walsh, Tosin Cole, and Mandip Gill. Chris Chibnall served as the showrunner. A common mix-up is calling Whittaker the eleventh Doctor; she was the thirteenth, while season 11 refers to the eleventh series of the revived program that began in 2005.
