Romain Duris (; born 28 May 1974) is a French actor.
Duris was born in Paris, son of a father who is an engineer-architect and a mother who is a dancer. His father is related to Armand-Gaston Camus, an archivist who founded the Archives nationales. His mother is a descendant of 18th-century Swedish painter Alexander Roslin and his wife. Duris has a sister, pianist Caroline Duris, who played on the soundtrack of the film The Beat That My Heart Skipped (2005), in which he acted.
Duris studied arts at university but first decided to follow a career in music, forming a jazz-funk band. Music remains a major interest. Before going into acting, he started an acid-jazz band in which he was a drummer. In 1995, he was featured in a pop video for singer Princess Erika, "Faut qu'j'travaille" (I Need To Work), where he played the role of a small-time gangster.
Duris lives in Paris near La Bastille, with his actress girlfriend Olivia Bonamy. They have two sons.
In 1993, Duris was noticed by a casting director who saw him waiting in a queue. He offered the younger man a part in the Cédric Klapisch film Le péril jeune (1994).
Duris's additional collaborations with Klapisch include the Spanish Apartment Trilogy (L'Auberge Espagnole, The Russian Dolls, and Chinese Puzzle). He played a French exchange student Xavier Rousseau, which was one of his best-known roles because of the trilogy.
Duris gained international recognition for his performance in the film The Beat That My Heart Skipped (2005), directed by Jacques Audiard. He won the Lumière Award for Best Actor and received his first nomination for the César Award for Best Actor.
He has since gone onto become a major star in the French film industry and has starred in many successful and critically acclaimed films: Dans Paris (2006), Paris (2008), Heartbreaker (2010), The Big Picture (2010), Populaire (2012), Mood Indigo (2013), The New Girlfriend (2014), All the Money in the World (2017), The Animal Kingdom (2023), ' (2023) and ' (2023).
