Christopher Willcock (born 1947) is an Australian Jesuit priest and composer of liturgical music.
He then pursued doctoral studies in sacramental and liturgical theology at the Institut Catholique de Paris.
Collaborating with cartoonist and artist Michael Leunig, Willcock won the 2006 Classical Music Award for Choral or Vocal Work of the Year with excerpts from his work titled Southern Star (his cycle of nine Christmas carols composed in collaboration with Leunig).
He also gave the annual Slattery Lecture for the School of Philosophy and Theology at the University of Notre Dame Australia.
In 2004 he was appointed by the Melbourne Chorale as their first composer-in-residence and that year they performed two new a cappella pieces, Etiquette with Angels (a setting of a poem by another Australian Jesuit, Andrew Bullen) and his Latin setting of Psalm 50, Miserere (considered Psalm 51 in some versions of the Bible).
