Augustus Montague Summers (10 April 1880 – 10 August 1948) was an English author, clergyman, and teacher. He initially prepared for a career in the Church of England at Oxford and Lichfield, and was ordained as an Anglican deacon in 1908. He then converted to Roman Catholicism and began styling himself as a Catholic priest. He was, however, never affiliated with any Catholic diocese or religious order, and it is doubtful that he was ever actually ordained to the priesthood. He was employed as a teacher of English and Latin while independently pursuing scholarly work on the English drama of the 17th century. The latter earned him election to the Royal Society of Literature in 1916.
