Abraham Feinberg (14 September 1899 – 5 October 1986) was an American rabbi who lived much of his life in Canada. In his obituary, The New York Times declared about him: "He was always ready to march, lend his name or send a telegram if there was a protest for disarmament or for a treaty on a nuclear test ban, or against racism in South Africa, radical injustice in America and United States policy in Vietnam."
