New Luce (Scottish Gaelic: Baile Ùr Ghlinn Lus) is a civil parish in Dumfries and Galloway, south-west Scotland. It lies in the traditional county of Wigtownshire, and is about 10 miles (16 km) in length and 5 miles (8.0 km) in breath, being the upper part of the original Glenluce Parish. New Luce is shown as a civil parish on John Ainslie's county map of 1782. New Luce is also the principal village within the parish. The coast to coast walk, the Southern Upland Way, passes close to the village. The Covenanter Alexander Peden spent time preaching in the village.
