Brian O'Neill (Irish: Brian Ó Néill; c.1604 – 16 August 1617), also known as Bernard or Con Brian, was a seventeenth-century Irish noble and the youngest son of Hugh O'Neill, Earl of Tyrone. He joined his parents on the Flight of the Earls and was later found dead in Brussels, possibly killed by an English assassin.
