Gerard Charles Windsor (born 29 December 1944) is an Australian author and literary critic. He was dux of St Ignatius' College, Riverview in both 1961 and 1962, and a student of Melvyn Morrow. Windsor trained as a Jesuit from ages 18 to 24 before realizing it was not his vocation.
He studied Arts at the Australian National University and Sydney University, before briefly studying medicine. He is a writer, having published ten books, including fiction, compilations of essays, and memoirs. Awarded the 2005 Pascall Prize for Critical Writing, he noted that "The primary responsibility of the review is to entertain the reader...The primary responsibility is not to the book or the movie or the play or whatever, which is not to be utterly amoral about it. But nevertheless, it should be a work whole in itself, and give pleasure." Windsor's novel, I Have Kissed Your Lips, was shortlisted for the Age Book of the year Award and longlisted for the 2005 Miles Franklin Award.
