Sir Dirk Bogarde (born Derek Niven van den Bogaerde; 28 March 1921 – 8 May 1999) was an English actor, novelist, and screenwriter. Initially a matinée idol in films such as Doctor in the House (1954) for the Rank Organisation, he later acted in art-house films.

Bogarde came to prominence in films including The Blue Lamp in the early 1950s, before starring in the successful Doctor film series (1954–1963). He twice won the BAFTA Award for Best Actor in a Leading Role, for The Servant (1963) and Darling (1965). His other notable film roles included Victim (1961), Accident (1967), The Damned (1969), Death in Venice (1971), The Night Porter (1974), A Bridge Too Far (1977), and Despair (1978).
