Richard Óg de Burgh, Anglo-Irish noble and soldier, ancestor of Burke of Clanricarde, fl. early-to-mid 13th century.

De Burgh was a younger, illegitimate son, of William de Burgh (died 1205). He had brothers Richard Mór de Burgh, 1st Baron of Connaught (died 1243) and Hubert de Burgh, Bishop of Limerick (died 1250).

Richard Óge is considered the ancestor of the Burke family of Clanricarde in south Connacht (now County Galway, which became an extremely powerful family in their own right following the Burke Civil War of the 1330s.

According to volume nine of A New History of Ireland, "The origins of the Clanricard line are not abolsutely proven, but the descent given" (on page 170, see family tree below) "is that in the best Irish genealogical sources and is not contradicted by contemporary sources."
