Private James Frazer is a fictional Home Guard platoon member and undertaker, first portrayed by John Laurie in the BBC television sitcom Dad's Army. He is noted for his catchphrases "We're doomed!" and "Rubbish!"

John Paton Laurie was a Scottish stage, film, and television actor. He appeared in scores of feature films with directors including Alfred Hitchcock, David Lean, Michael Powell and Laurence Olivier, generally playing memorable small or supporting roles. As a stage actor, he was cast in Shakespearean roles and was a speaker of verse, especially of Robert Burns. He is perhaps best remembered for his role in the sitcom Dad's Army (1968–1977) as Private Frazer, a member of the Home Guard.
