Jay Peak is a mountain located about 5 miles south of the Canada–US border, in Jay and Westfield, Orleans County, Vermont, of which it is the highest point. Most of the mountain is in Jay State Forest. The mountain is named for the town of Jay, Vermont, in which much of the mountain except the peak area itself is located. The town of Jay is in turn named for John Jay, the first Chief Justice of the United States and a local landholder. Jay Peak is part of the northern Green Mountains.
