James Robert "Jamie" Bruce Lockhart (14 March 1941 – 27 October 2018) was a British diplomat, intelligence officer, author, and artist. The son of diplomat J. M. Bruce Lockhart and grandson of Scottish rugby international John Bruce Lockhart, he gained a modern languages degree from the University of Cambridge before beginning a career with the Foreign Office. However, this work was in fact a cover for his real work with the Secret Intelligence Service (MI6). In later years, Lockhart became a published author, with works including a biography of Hugh Clapperton and a book about life in an English preparatory school. He was the father of actor Dugald Bruce Lockhart.
