Jacob Burck (née Yankel Boczkowsky, January 10, 1907 – May 11, 1982) was a Polish-born Jewish-American painter, sculptor, and award-winning editorial cartoonist. Active in the Communist movement from 1926 as a political cartoonist and muralist, Burck quit the Communist Party after a visit to the Soviet Union in 1936, deeply offended by political demands there to manipulate his work.
