The Donmar Warehouse is a 251-seat, not-for-profit theatre in Covent Garden, London, England. It first opened on 18 July 1977.
Sam Mendes, Michael Grandage and Josie Rourke have all served as artistic director, a post held since 2019 by Michael Longhurst. The theatre has a diverse artistic policy that includes new writing, contemporary reappraisals of European classics, British and American drama and small-scale musical theatre.
As well as presenting at least six productions a year at its home in Covent Garden, every year the Donmar tours one in-house production in the UK.
