James Gregory (7 November 1941 – 2003) was the censor officer and prison guard of Nelson Mandela for many years of his captivity. He later wrote the book Goodbye Bafana: Nelson Mandela, My Prisoner, My Friend, on which the 2007 film Goodbye Bafana was based. The book, and later the film, are based on the idea that Gregory and Mandela had developed a friendship despite being prison guard and prisoner, respectively.
