Peter Knight (born 27 May 1947) is a folk musician, a former member of British folk rock group Steeleye Span. Born in London, as a child Knight learned the violin and mandolin before going to the Royal Academy of Music from 1960 to 1964. The recordings of the Irish fiddler Michael Coleman inspired him to take part in Irish pub sessions. He teamed up with guitarist and singer Bob Johnson until 1970 when he joined Steeleye Span. The parting was short-lived, as Johnson himself also joined Steeleye Span in 1972.
