Sean Delaney is a British-born actor of Irish descent. He was born in London. After finishing high school, Delaney trained at the Royal Academy of Dramatic Art, from which he graduated in 2015.
Delaney made his stage debut in Beth Steel's messy but compelling drama Labyrinth that was produced at the Hampstead Theatre in 2016, earning a place on the Evening Standard's Theatre Emerging Talent Award list. The same year, he played Jason in David Lindsay-Abaire's Pulitzer Prize-winning drama Rabbit Hole, also at the Hampstead Theatre.
Delaney made his TV debut as a guest in a Midsomer Murders episode in 2016.
In 2018, he played Michael Carney in Jez Butterworth's hit play The Ferryman, directed by Sam Mendes and staged in the Gielgud Theatre. Subsequently, he was invited to work in the Stateside production of the play that was staged on Broadway's Bernard B. Jacobs Theatre.
Delaney is best known for portraying Kenny Stowton, an ex-hacker recruited by MI6, in BBC's hit black comedy-spy thriller TV series Killing Eve from 2018 to 2020. His quirky, fan-favorite character started off as a temporary one but turned into a re-occurring and quite integral part of the hit show. Head writer Suzanne Heathcote rated his work in the series as "brilliant".
He made his film debut in 2021 playing Young Detective Mulligan in the American superhero film Venom: Let There Be Carnage.
In 2022, he starred as Teddy Todd in BBC Two's adaptation of Kate Atkinson's novel Life After Life.
He is currently working in the upcoming Charlie Stratton-directed film Seacole, along with Sam Worthington, Gugu Mbatha-Raw, and Rupert Graves.
