Crotched Mountain is a small mountain in western Hillsborough County, New Hampshire, in the United States. The 2,063-foot (629 m) summit of the mountain is in the town of Francestown, while the western slopes of the mountain rise in the town of Bennington, and a long southern ridge of the mountain is in Greenfield. The mountain was named for its appearance. Early settlers thought its V-shaped peaks resembled the fork or "crotch" of a tree.
