Mount Franklin is a mountain in Coös County, New Hampshire, United States.

Mount Franklin drains on the northwest side into the Ammonoosuc River, thence into the Connecticut River and into Long Island Sound in Connecticut.

The Appalachian Trail, a 2,170-mile (3,490 km) National Scenic Trail from Georgia to Maine, crosses Mount Franklin as it traverses the main ridge of the Presidentials from Crawford Notch to the summit of Mount Washington.

Franklin stands on the northwest side of the Dry River Wilderness.

Although well over 4,000 feet (1,200 m) in height, the Appalachian Mountain Club doesn't consider Franklin a "four-thousand footer" because it stands no more than 65 feet (20 m) above the col on the ridge from Mount Monroe, making it a secondary summit of that peak.
