Dan Stevens is an English actor and producer. He is best known internationally for his role as Matthew Crawley in the British period drama television series Downton Abbey.

In 2004, Stevens began his professional acting career when Peter Hall cast him as Orlando in his touring production of Shakespeare's As You Like It. The tour took the production to the Rose Theatre in Kingston upon Thames, the Brooklyn Academy of Music in New York City, the Curran Theatre in San Francisco, and the Ahmanson Theatre in Los Angeles. His debut performance earned him glowing reviews from prominent critics in England and the United States, as well as a commendation at the 2004 Ian Charleson Awards.

In 2006, Stevens starred as Nick Guest in the BBC adaptation of Alan Hollinghurst's Booker Prize-winning novel The Line of Beauty. Later that year he played Simon Bliss in Hay Fever by Noël Coward at London's Haymarket Theatre, alongside Peter Bowles and Dame Judi Dench; the director was Peter Hall. He also performed as Lord Holmwood in an adaptation of Dracula for the BBC, and as Basil Brookes in the BBC Emmy-award-winning film, Maxwell.

In 2008, Stevens appeared in the BBC adaptation of Jane Austen's novel, Sense & Sensibility, playing Edward Ferrars, and the West End revival of Noël Coward's The Vortex.

In June 2009 he returned to the West End, playing Septimus Hodge in an acclaimed revival of Tom Stoppard's Arcadia at the Duke of York's Theatre.

In 2010, Stevens got his biggest break when he was cast as Matthew Crawley in the ITV series Downton Abbey, created and written by Oscar-winning screenwriter Julian Fellowes. The series went on to be a global sensation, and has been nominated for several Emmy, BAFTA, Golden Globe and Screen Actors Guild Awards since its debut. The central love story of Matthew Crawley and his distant cousin, Lady Mary Crawley, played by Michelle Dockery, was enormously popular. Stevens left the series after finishing the third season and the Christmas Special in 2012. His exit caused a huge uproar with fans, who vented on social media in dismay at his beloved character's untimely death.

In 2012, Stevens moved with his family to New York City to make his Broadway debut opposite Jessica Chastain and David Strathairn in The Heiress. He has narrated over 30 audiobooks, including Casino Royale, Wolf Hall, and War Horse. In 2014, he was nominated for two Audie Awards, in the Classic category and Solo Narration (Male) category for Frankenstein.
