Geoffrey John Cuming (1917 – 24 March 1988) was a Church of England clergyman, liturgist, and music historian. After being permanently injured during his British Army service prior to the Battle of Arnhem, Cuming was ordained a priest. He authored and edited several nonfiction texts on music and Christianity.
During and after Second World War, Cuming collaborated with Francis F. Clough to compile the World's Encyclopedia of Recorded Music, a major discography first published in 1952. On Christian liturgy, Cuming's work included The Durham Book on John Cosin's 17th-century proposed liturgy and A History of Anglican Liturgy. His works on Early Christian liturgies included collaboration with Ronald Jasper and a posthumously published text on the Liturgy of Saint Mark.
Cuming was an advisor to the Church of England's committees charged with producing new liturgical texts which produced the Alternative Service series, Alternative Service Book, and Common Worship. He also served as an editorial secretary for the Alcuin Club, vice-principal at St John's College, Durham, and on the faculty of both Ripon College Cuddesdon and the Church Divinity School of the Pacific.
