William Shuler Harris (1865–1956) was an American Evangelical minister, author, and social commentator. Born in New Columbia, Pennsylvania, he entered the ministry in 1888 and served churches in Pennsylvania and Kansas before retiring in 1939.
Harris wrote widely on religion, morality, social reform, and the problems of industrial society. His writing frequently combined Christian allegory, satire, speculative fiction, and social criticism.
Harris remained active as a writer and minister into old age and was also a keen chess player. He died in Allentown, Pennsylvania, in 1956, aged 90.
