Earl of Clanwilliam is a title in the Peerage of Ireland. It was created in 1776 for John Meade, 1st Viscount Clanwilliam. The Meade family descends from Sir John Meade, who represented Dublin University and County Tipperary in the Irish House of Commons and served as Attorney-General to James, Duke of York. In 1703, he was created a Baronet, of Ballintubber in the County of Cork, in the Baronetage of Ireland. His eldest son, Pierce, the second Baronet, died unmarried at an early age and was succeeded by his younger brother Richard, the third Baronet. Richard represented Kinsale in the Irish Parliament.

The Peerage of Ireland consists of those titles of nobility created by the English monarchs in their capacity as Lord or King of Ireland, or later by monarchs of the United Kingdom of Great Britain and Ireland. It is one of the five divisions of Peerages in the United Kingdom. The creation of such titles came to an end in the 19th century. The ranks of the Irish peerage are duke, marquess, earl, viscount and baron. As of 2016, there were 135 titles in the Peerage of Ireland extant: two dukedoms, ten marquessates, 43 earldoms, 28 viscountcies, and 52 baronies. However, these titles have no official recognition in the Republic of Ireland, with Article 40.2 of the Constitution of Ireland forbidding the state conferring titles of nobility and stating that an Irish citizen may not accept titles of nobility or honour except with the prior approval of the Irish government.
