List of vice-admirals of Ulster
This is a list of the vice-admirals of Ulster, a province in the north of Ireland. Prior to 1585 the whole of Ireland was served by a single vice-admiral, namely Thomas Radcliffe, 3rd Earl of Sussex (1558–1565), Gerald Fitzgerald, 11th Earl of Kildare (1564–1573) and Thomas Butler, 10th Earl of Ormonde (1585). Separate vice-admiralties were then established for Munster in 1585, for Ulster by 1602, for Leinster by 1612 and for Connaught by 1615. Vice-admirals of Ulster. Source (1602–61): Source (1661–:
