Thomas Radcliffe, 3rd Earl of Sussex, was an English nobleman who came to Ireland in 1556 as Lord Deputy and after 1560 as Lord Lieutenant. In an attempt to subdue Shane O'Neill he burnt Armagh, and three years later he again made the attempt as part of a venture undertaken jointly with the O'Donnells and the Maguires, but failed. He reneged on his promise not to implement the Act of Supremacy, and three years later used the act to dissolve parliament.
