Richard Butler, 2nd Earl of Glengall

Richard Butler, 2nd Earl of Glengall (17 May 1794 – 22 June 1858), styled Viscount Cahir between 1816 and 1819, was an Irish Tory politician and peer.

He was the son of Richard Butler, 1st Earl of Glengall and Emily Jefferys. On 17 July 1818 he was elected as the Member of Parliament for Tipperary. Seven months later he succeeded to his father's title and resigned his seat. On 1 September 1829 he was elected as an Irish representative peer, and took his seat in the House of Lords on the Tory benches.

On 20 February 1834 he married Margaret Lauretta Mellish, and together they had two daughters. Having no male issue, his titles (including the Cahir Barony of 1583) became extinct upon his death in 1858.
