Baron Cloncurry, of Cloncurry in the County of Kildare, was a title in the Peerage of Ireland. It was created on 29 December 1789 for Sir Nicholas Lawless, 1st Baronet, who had earlier represented Lifford in the Irish House of Commons. He had already been created a Baronet, of Abington in the County of Limerick, in the Baronetage of Ireland on 6 August 1776. He was succeeded by his son, the second Baron. On 14 September 1831 he was created Baron Cloncurry, of Cloncurry in the County of Kildare, in the Peerage of the United Kingdom. He had divorced his first wife, Elizabeth Georgiana Morgan, in 1811 after a particularly scandalous lawsuit, on the ground of her adultery with Sir John Piers, 6th Baronet.
