Anthony Milner (13 May 1925 – 22 September 2002) was a British composer, teacher and conductor.
Milner was born in Bristol, and educated at Douai School, Berkshire. He was awarded a bursary to attend the Royal College of Music, where he studied piano with Herbert Fryer and theory with R. O. Morris. He studied composition privately with Mátyás Seiber. Milner's own teaching career began at Morley College, London, where he taught music theory and history from 1948–64. He was Lecturer in Music at King's College London, from 1965–71, when he moved to Goldsmiths' College as Senior Lecturer, becoming Principal Lecturer in 1974. In 1980 he was appointed full-time Principal Lecturer at the Royal College, where he had taught part-time since 1961. He remained in this post until his retirement in 1989.
Milner had close academic ties with North America. Beginning in 1964, he gave frequent summer lecture tours in the USA and Canada. Milner's teaching interests centred on twentieth-century British music and on sacred and liturgical music. He was Composer-in-Residence at the Summer School of Liturgical Music at Loyola University New Orleans in 1965 and 1966, and the first Director of Spode Music Week, an annual residential Music school that places particular emphasis on the music of the Roman Catholic liturgy.
In 1985 Pope John Paul II appointed Anthony Milner a Knight of St. Gregory, in recognition of his work for Catholic liturgical music.
