There have been three baronetcies created for members of the Assheton family (pronounced Ashton), two in the Baronetage of England and one in the Baronetage of the United Kingdom. Two of the creations are extinct while one is extant.
The Assheton family, alternatively spelled Ashton, descends from Ashton-under-Lyne and can be traced to the 10th century. The military commander Sir John de Assheton (or de Ashton) was among their ancestors.
The Assheton Baronetcy, of Lever in the County of Lancaster, was created in the Baronetage of England on 28 June 1620 for Ralph Assheton. The second Baronet sat as Member of Parliament for Clitheroe. The title became extinct on the death of the fourth Baronet in 1696.
The Assheton Baronetcy, of Middleton in the County of Lancaster, was created in the Baronetage of England on 17 August 1660 for Ralph Assheton. The second Baronet sat as Member of Parliament for Liverpool and Lancashire. The title became extinct on the death of the third Baronet in 1765.
