Earl of Dumfries is a title in the Peerage of Scotland. It was originally created for William Crichton, 9th Lord Crichton of Sanquhar, in 1633, and stayed in the Crichton family until the death of the fourth countess in 1742, at which point the title passed to first the Dalrymple and then the McDouall families before finally being inherited by the Marquesses of Bute, where it remains today.
