Simon Langton (born 5 November 1941 in Amersham, Buckinghamshire) is a television director and producer. He is the son of David Langton, the actor who played Richard Bellamy in Upstairs, Downstairs.
After he had directed a number of TV drama series and serials during the 1970s, his 1982 dramatisation of the John le Carré novel Smiley's People was nominated for both a BAFTA award in the UK, and an Emmy Award in the USA. He later won a BAFTA award for the 1989 series Mother Love, starring Diana Rigg.
He is perhaps best known for directing the adaptation of Pride and Prejudice starring Colin Firth and Jennifer Ehle in 1995, for which he was also nominated for a BAFTA.
He continues to direct for British TV drama, having lately directed a number of episodes of Rosemary and Thyme and Midsomer Murders.
