Paul Morrissey (February 23, 1938 - October 28, 2024) was an American film director, best-known for his association with Andy Warhol.

Morrissey attended Ampleforth College, a private Roman Catholic boarding school and Fordham University, both Roman Catholic schools, and later served in the United States Army. A political conservative and self-described "right-winger", who has publicly protested against what he perceives as immorality and "anti-Catholicism", Morrissey's long-term collaboration with the low-keyed, apparently apolitical Warhol was viewed by many as "a successful mismatch", although both men did share some traits, i.e. both were practising Catholics from "ethnic" backgrounds (Warhol was of Rusyn descent and Morrissey is of Irish descent).
