There have been two baronetcies created for persons with the surname Simpson, both in the Baronetage of the United Kingdom. Both creations are extinct. The Simpson Baronetcy, of Strathavon in the County of Linlithgow, and of the City of Edinburgh, was created in the Baronetage of the United Kingdom on 3 February 1866 for the Scottish physician James Young Simpson. The title became extinct on the death of the third Baronet in 1924.
