Doctor Foster is a British psychological thriller television series inspired by the ancient Greek myth of Medea which debuted on BBC One on 9 September 2015. Created and written by Mike Bartlett, it stars Suranne Jones as Gemma Foster, a doctor who suspects her husband Simon (Bertie Carvel) is having an affair.

The second series started on 5 September 2017 and concluded on 3 October 2017. Both series were critical and ratings successes, and the programme was remade in multiple countries. A spin-off, Life, featuring the character of Anna Baker, aired in 2020. A potential third series remained uncertain for years: Jones initially citied incompatibility of schedules. Bartlett said while there is more to explore with Gemma Foster's story, he would bring the show back only if there were a vital story to be told. On 25 February 2026, it was finally confirmed that the show would be returning for a third and final series.

Reception In general, the show has received acclaim. The opening episode received generally positive reviews from critics, with Lucy Mangan from The Guardian calling it a "gripping portrait of a marriage slowly being poisoned," although Mangan expressed fears of the show descending into "melodrama in the not too distant future". In a review for The Daily Telegraph, Michael Hogan gave the drama four stars out of five, describing it as "an edgy nail-biter" that was "sparkily written by Olivier Award-winner Mike Bartlett", despite a soundtrack that was "overbearing".

Less enthusiastically, Victoria Segal of The Sunday Times wrote of the fourth episode that it "clattered unsteadily to its denouement ...this episode is as desperately uneven as the rest of the series, thrashing about between high melodrama and muted misery." Catherine Blythe of The Telegraph bemoaned its "absurd plot" and the lack of "emotional logic" in a series of "melodramatic contortions that required a character who was supposed to be brainy to act like an utter fool".
