Baron Bourke of Brittas (Irish: Barún Búrc de Brittas; English: /bɜːrk/; BURK), of the County of Limerick, was a title in the Peerage of Ireland created on 17 February 1618 for Theobald Bourke.

Theobald Burke was the son of Theobald Bourke, son of William Bourke, 1st Baron Bourke of Castleconnell (see Baron Bourke of Castleconnell) and Lady Mary Burke. He was the younger brother of John Bourke, 2nd Baron Bourke of Castleconnell, and Richard Bourke, 3rd Baron Bourke of Castleconnell. The third Baron was attainted in 1691 due to his loyalty to James II of England. The title was consequently forfeited.^[2]
