O'Rourke (Irish: Ó Ruairc) is an Irish Gaelic clan based most prominently in what is today County Leitrim. The family were the historic rulers of Breifne and later West Breifne until the 17th century. The O'Rourke Clan Chief was at odds with the O'Reilly Chief because both clans contested each other for the title Prince of Breifne. The O'Rourke chief was seated at O'Rourke's Tower House which was on the north side of Lough Gill, County Leitrim, and which is now Parke's Castle.
