There have been three baronetcies created for members of the Anstruther family, two in the Baronetage of Nova Scotia and one in the Baronetage of Great Britain. Two of the creations are extant while one is extinct.
The Anstruther Baronetcy, of Wrae in the County of Linlithgow and of Balcaskie, Fife and Braemore in the County of Caithness, was created in the Baronetage of Nova Scotia on 28 November 1694 for Robert Anstruther, subsequently Member of Parliament for Fifeshire. The fifth Baronet represented Fifeshire and St Andrews in Parliament. The sixth Baronet was Lord Lieutenant of Fife. The seventh Baronet succeeded his kinsman as twelfth Baronet of Anstruther in 1980 (see below). The titles have remained united ever since.
The Anstruther, later Anstruther-Paterson, later Carmichael-Anstruther, later Anstruther Baronetcy, of Anstruther in the County of Lanark, was created in the Baronetage of Nova Scotia on 6 January 1700 for John Anstruther, Member of Parliament for Anstruther Burghs and Fifeshire. The second and third Baronets also represented Anstruther Burghs in Parliament. The third Baronet married Anne Paterson, daughter of Sir John Paterson, 3rd Baronet, and assumed the additional surname of Paterson. The fourth Baronet was created a baronet, of Anstruther in the County of Lanark, in the Baronetage of Great Britain on 18 May 1798, ten years before succeeding his elder brother in the baronetcy of 1700. In contrast to his brother he did not assume the surname of Paterson. The fifth Baronet succeeded to the Carmichael estates on the death of his kinsman Andrew Carmichael, 6th Earl of Hyndford, in 1817, and assumed the additional name of Carmichael. The eighth Baronet represented Lanarkshire South in Parliament. On the death of the eleventh Baronet in 1980 the baronetcy of 1798 became extinct. The late Baronet was succeeded in the baronetcy of 1700 by his kinsman, Sir Ralph Hugo Anstruther, 7th Baronet, of Wrae, Balcaskie, Fife and Braemore (see above). The titles remained united.
