The Bradstreet Baronetcy, of Castilla in County Dublin was created in the Baronetage of Ireland on 14 July 1759 for Simon Bradstreet. His son, the second Baronet died without male issue in 1773 and was succeeded by his younger brother, a Member of Parliament for Dublin in the Irish House of Commons, and later a judge. The fourth baronet was a barrister. The latter's elder son, the fifth Baronet died childless in 1889 and the title went to his younger brother. With the death of the seventh Baronet in 1924, the baronetcy became extinct.
