Mark Barkworth (alias Mark Lambert) was a Catholic priest and martyr (c. 1572 – 1601). Born around 1572 at Searby, Lincolnshire, he studied for a time at Oxford, though no record remains of his stay there. Originally raised as a Protestant, he was received into the Catholic Church at Douai in 1593, by Father George, a Flemish Jesuit and entered the College there with a view to the priesthood. He matriculated at Douai University on 5 October 1594. Barkworth was beatified by Pope Pius XI on 15 December 1929.
