The Mad River is a tributary to the Winooski River in Vermont. It has its headwaters in Granville Gulf, then flows north through the towns of Warren, Waitsfield, and Moretown before entering the Winooski River just downstream from Middlesex. Other towns within the Mad River watershed are the entire Town of Fayston and a portion of the Town of Duxbury. Relative to other rivers in the state, the Mad River is fairly rocky and clear, making it a popular for swimming. In the summer of 2008, didymo, or rock snot, was found in the upper portions of the river.
