The title Earl of Dysart was created in 1643 in the Peerage of Scotland, along with the title Lord Huntingtower. The first Earl, William Murray, died without male issue, so the titles became extinct. However, in 1670, his daughter Elizabeth received a re-grant of both titles, with the provision that, for the purposes of precedence or seniority, they would be treated as having been created in 1643.

The surname associated with the earldom has sometimes changed due to the marriage of female holders of the title.
