Clanricarde (English: /klænˈrɪkɑːrd/ klan-RIK-ard), also known as Mac William Uachtar (Upper Mac William) or the Galway Burkes, were a fully Gaelicised branch of the Hiberno-Norman House of Burgh who were important landowners in Ireland from the 13th to the 20th centuries.
Territories Clannricarde claimed dominion over included Uí Maine, Kinela, de Bermingham's Country, Síol Anmchadha and southern Sil Muirdeagh were at times at war.
The Richard in question was Richard Mór de Burgh, 1st Lord of Connacht (died 1243), son of William de Burgh, whose great-great-grandson became the first Clanricarde in the 1330s.
It was a Gaelic title meaning "son of the upper William (de Burgh)".
However, it was never used as popularly as the term Clanricarde and was in any case abandoned by the end of the 16th century.
