Westmore Vermont is a town in Orleans County, located in the beautifully scenic Northeast Kingdom of Vermont, an area that National Geographic selected as part of their geotourism program for sustainable destinations. Westmore is the least populated town in the county.

Westmore contains one unincorporated village clustered around Lake Willoughby, which is a glacial lake over 300 feet (91 m) deep in places, and the deepest lake entirely contained in the state. In 2010, Yankee magazine named Willoughby as the third best lake in New England.
