Richard Keith Johnson (30 July 1927 – 6 June 2015) was an English stage and screen actor, writer and producer. Described by Michael Coveney as "a very 'still' actor – authoritative, calm and compelling," he was a staple performer in British films and television from the 1960s until the 2010s, often playing urbane sophisticates and authoritative characters. He had a distinguished theatrical career, notably as a cornerstone member of the Royal Shakespeare Company, and was once acclaimed as "the finest romantic actor of his generation."

Johnson was born to Frances Louisa Olive (née Tweed) and Keith Holcombe Johnson in Upminster, Essex, in 1927.

Johnson went to Felsted School, and wanted to act instead of going into the family paint business. He trained at RADA and due to the manpower shortage of wartime made his first professional appearance relatively quickly, on stage in Manchester with John Gielgud's company in a production of Hamlet in 1944.

He served in the Royal Navy from 1945 to 1948.

Johnson made his screen debut in an adaptation of Tusitala for BBC Sunday-Night Theatre. He made his film debut with an uncredited part in Captain Horatio Hornblower (1951) and was also uncredited in Calling Bulldog Drummond (1951).

He was at the Shakespeare Memorial Theatre from 1952 to 1957. "It was an electric time to be in that company", he later recalled.

Johnson played Mr. Wickham in a 1952 TV adaptation of Pride and Prejudice (with Peter Cushing as Darcy) and was D'Artagnan in a TV adaptation of The Three Musketeers (1952). He could be seen in Lady in the Fog (1952), "The Mayor of Torontal" for Wednesday Theatre (1952), The Heir of Skipton (1953), Saadia (1953) for MGM, A Party for Christmas (1954), The Queen Came By (1954), "The Rescue" for ITV Television Playhouse, "The Orderly" for Theatre Royal, and Plaintiff in a Pretty Hat (1955).

In 1955, he was in The Lark, by Jean Anouilh, with Dorothy Tutin.
