Vermont Route 108 is a north–south state highway in northern Vermont, United States. Its southern terminus is at VT 100 in Stowe, and its northern terminus is at the Canadian border in Franklin, where it continues into Quebec as Route 237. VT 108 is 45.450 miles (73.145 km) long.

VT 108 passes through the area of the Mount Mansfield State Forest. It starts in Stowe and goes through Smugglers' Notch to Jeffersonville. The road cuts through Mount Mansfield. The road is very steep and turning, making impossible to plow in the winter. Tractor-trailers are barred from this section, and large straight trucks, buses and RVs are strongly encouraged to find other routes year-round. However, skiers come from alternate routes to cross-country, downhill ski, and snow mobile in the Smuggler's Notch Resort. Along the road, there are small parking areas where rock climbing and hiking are popular.
