Maurice FitzGerald I, 2nd Lord of Offaly (1194 – 20 May 1257) was a Norman-Irish peer, soldier, and Justiciar of Ireland from 1232 to 1245. He mustered many armies against the Irish, and due to his harsh methods as Justiciar, he received criticism from King Henry III of England. He was succeeded as Lord of Offaly by his son, Maurice FitzGerald, 3rd Lord of Offaly.
