The Mull of Galloway is the southernmost point of Scotland. It is situated in Wigtownshire, Dumfries and Galloway, at the end of the Rhins of Galloway peninsula.

Wigtownshire or the County of Wigtown is one of the historic counties of Scotland, covering an area in the south-west of the country. Until 1975, Wigtownshire was an administrative county used for local government. Since 1975 the area has formed part of Dumfries and Galloway for local government purposes. Wigtownshire continues to be used as a territory for land registration, being a registration county. The historic county is all within the slightly larger Wigtown Area, which is one of the lieutenancy areas of Scotland and was used in local government as the Wigtown District from 1975 to 1996.
