Wilmot is a town in Merrimack County, New Hampshire, United States. The population was 1,407 at the 2020 census. The town includes the communities of Wilmot, Wilmot Flat, and North Wilmot.

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. Dr. Wilmot was rector at Barton-on-the-Heath in Warwickshire, England.

Wilmot is in northwestern Merrimack County, in the Dartmouth–Lake Sunapee Region of New Hampshire. According to the United States Census Bureau, the town has a total area of 29.6 square miles (76.7 km), of which 29.4 square miles (76.2 km) are land and 0.2 square miles (0.5 km), or 0.70%, are water. Wilmot is drained by Cascade Brook (two branches), Kimpton Brook, and Frazier Brook, all of which flow to the Blackwater River in neighboring Andover. The entire town is part of the Merrimack River watershed. Wilmot is dotted with several large ponds, including Eagle, Butterfield, Piper, White, Tannery, and Chase ponds. The Sunapee–Ragged–Kearsarge (SRK) Greenway traverses the town, crossing Bog Mountain in the northern part of town and climbing Mount Kearsarge in the south.

The village of Wilmot is near the center of the town, along New Hampshire Route 4A. Wilmot Flat is a village in the southern part of the town, served by New Hampshire Route 11. North Wilmot is a rural community centered on the junction of North Wilmot Road and Breezy Hill Road, north of White Pond.

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.

The town is the home of Camps Kenwood and Evergreen on Eagle Pond.
