Baron Massy

Baron Massy, of Duntrileague in the County of Limerick, is a title in the Peerage of Ireland. It was created in 1776 for Hugh Massy, who had previously represented County Limerick in the Irish House of Commons. His son, the second Baron, also represented this constituency in the Irish Parliament. His great-grandson, the sixth Baron, sat in the House of Lords as an Irish Representative Peer from 1876 to 1915. As of 2010 the title is held by the latter's great-great-grandson, the tenth Baron, who succeeded his father in 1995.

Eyre Massey, 1st Baron Clarina, was the younger brother of the first Baron Massy.
