Mark Starr (27 April 1894, Shoscombe – 24 April 1985, New York City) was a British American labor historian and pedagogue. For 25 years he was educational director of the International Ladies Garment Workers Union. Along with the Horrabins, Starr briefly joined the Communist Party of Great Britain during the early 1920s, but soon left, unable to stomach the group's discipline. A trip to Leningrad in 1926 to attend an Esperanto conference further alienated him from the Soviets. He stood as a Labour Party candidate for Wimbledon in 1923 and 1924, obtaining about 30% of the vote each time.
