Antrim is a town in Hillsborough County, New Hampshire, United States. The population was 2,651 at the 2020 census. The main village in the town, where 1,395 people lived at the 2020 census, is defined as the Antrim census-designated place (CDP) and is located at the intersection of U.S. Route 202 and New Hampshire Route 31. The town of Antrim also includes the villages of Antrim Center, North Branch, and Clinton Village.


Settled in 1741 and incorporated on 22 March 1777, this town did not get its incorporated name until 1778. It was named for County Antrim in northern Ireland, which was the native home of the land's owner, Philip Riley. Scots-Irish settlers established a Presbyterian church in Antrim in 1788.

With falls providing water power, Great Brook was once lined with over twenty mills along its course from Gregg Lake to the Contoocook River. Commercial development centered on South Antrim. Cutlery was the major industry in this town, beginning with the manufacturing of apple-paring machines in 1864. The manufacture of cutlery continued in Antrim through 1989. The town is now largely a bedroom community for Peterborough and Hillsborough. It was home to the now-defunct Nathaniel Hawthorne College.


According to the United States Census Bureau, the town has a total area of 36.5 square miles (95 km2), of which 35.7 sq mi (92 km2) is land and 0.8 sq mi (2.1 km2) is water, comprising 2.27% of the town. Antrim is drained by the Contoocook River and its North Branch, in addition to Great Brook. Gregg Lake and Willard Pond are in the west. Bald Mountain, elevation 2,037 feet (621 m) above sea level and the highest point in Antrim, is also in the west. Antrim lies fully within the Merrimack River watershed.

The town center, defined as a census-designated place (CDP), covers an area of 4.5 square miles (12 km2), about 12% of the area of the town.
