Wilmot is a town in Merrimack County, New Hampshire, United States.

Incorporated in 1807 from part of New London, the Kearsarge gore, and a small piece of New Chester (later renamed Hill), the town took its name from Dr. James Wilmot, an English clergyman who had spoken out against England's treatment of the American colonies.

Wilmot Flat is a village in the southern part of the town, served by New Hampshire Route 11.

Mount Kearsarge, elevation 2,931 feet (893 m) above sea level, on the southern border, is the highest point in town and in Merrimack County.

Winslow State Park, at the northern foot of the mountain, provides access by two hiking trails to the summit.

The state park and the Winslow Trail are named after Captain John Winslow, the commander of the USS Kearsarge, which in June 1864 sank the CSS Alabama in the English Channel in a famous Civil War sea battle.
