Earl of Clanricarde (English: /klænˈrɪkɑːrd/; klan-RIK-ard) is a title that has been created twice in the Peerage of Ireland, first in 1543 and again in 1800. The former creation became extinct in 1916 while the 1800 creation is extant and held by the Marquess of Sligo since 1916. Clanricarde was a Gaelic title meaning "(head of) Richard's family" (also known as Mac William Uachtar/Upper Mac William) and this family were descended from Richard Mór de Burgh, 1st Lord of Connacht (d.1243), son of William de Burgh (d.1205/6), founder of the de Burgh/Burke family in Ireland.
