Grafton Notch is a notch, or mountain pass, located in Oxford County, Maine. The notch demarks the northeastern end the Mahoosuc Range, and thus of the White Mountains.
North of the height of land, the notch drains into the Swift Cambridge River, thence into the Dead Cambridge River and Umbagog Lake, the source of the Androscoggin River, which drains into Merrymeeting Bay, the estuary of the Kennebec River, and thence into the Gulf of Maine. To the south, the notch drains into the Bear River, thence into the Androscoggin.
Maine's Grafton Notch State Park includes the land along the bottom of the notch, and extends as far south as the summit of Old Speck Mountain on the southwest side of the notch. On the northeast side, it includes the lowest slopes of Baldpate Mountain. The Appalachian Trail, a 2,170-mile (3,500-km) National Scenic Trail from Georgia to Maine, crosses the notch between Old Speck and Baldpate.
