George Alexander McGuire (28 March 1866 – 10 November 1934) is best known for his prominence in Marcus Garvey's Universal Negro Improvement Association (UNIA). McGuire was elected in 1920 as Chaplain-General of the UNIA and wrote important documents about black ritual and catechism, drawing from his knowledge of religion and African history. Both he and Garvey were immigrants to the United States from Caribbean islands who had a vision of Pan-African goals.
