Leswalt (Scottish Gaelic: Lios Uillt) is a village and civil parish in Dumfries and Galloway, south-west Scotland.

It lies between Portpatrick and Stranraer in the Rhins of Galloway, part of the traditional county of Wigtownshire.

[citation needed] In ancient times it belonged to the monks of Tongland Abbey.

Andrew Agnew had been made hereditary constable of Lochnaw Castle by William Douglas of Leswalt in 1426.

The Old Kirk of Leswalt, now ruined, is of medieval origin, having been given to the monks of Tongland Abbey in the 14th century.

[5] The present castle incorporates a 16th-century tower house, but is largely the result of remodelling in the 18th century.

George Wilson's Archaeological and Historical Collections relating to Ayrshire and Galloway list forts in Leswalt.
