The Other Bennet Sister is a British period drama television series produced by Bad Wolf for BBC One. It is an adaptation of the novel of the same name by Janice Hadlow based on characters created by Jane Austen, with Ella Bruccoleri as Mary Bennet. The series premiered on 15 March 2026.
The first part of the series follows the events from Pride and Prejudice from Mary Bennet's point of view, before the story departs from that to follow Mary as she travels to London and the Lake District and the overlooked sister from the big Bennet family has a romantic adventure in Regency England.
The ten-part series is adapted by Sarah Quintrell from the 2020 novel of the same name by Janice Hadlow, based around the character Mary Bennet from the Jane Austen novel Pride and Prejudice, with Maddie Dai also writing an episode. It is lead directed by Jennifer Sheridan.
It is produced by Bad Wolf, for whom Dan McCulloch developed the project. Quintrell and Hadlow are executive producers with Kate Crowther, Becca Kinder and Jane Tranter as executive producers for Bad Wolf and Rebecca Ferguson as executive producer for the BBC. Sony Pictures Television has global rights. In May 2025, BritBox was announced as co-producer, with broadcasting rights in the U.S. and Canada.

Critics' reviews have been generally favourable. In a 5-star review for The Telegraph, Anita Singh described it as "a thing of pure delight". In a 3-star review for The Guardian, while Lucy Mangan found it "too slight a thing even for the pre-watershed Sunday evening slot", she concluded that "the growing charm and heft ... make it one worth sticking with".
