Mary Josephine Lavin (10 June 1912 – 25 March 1996) was a noted Irish short story writer and novelist. She is regarded as a pioneering female author in the traditionally male-dominated world of Irish letters. Her subject matter often dealt explicitly with feminist issues and concerns at a time when the primacy of the Roman Catholic Church and its abuses (e.g. the Magdalene Laundries) impinged extensively on Irish society.
