North Haverhill is an unincorporated community in the town of Haverhill in Grafton County, New Hampshire, United States. It is one of several villages in the town of Haverhill and is the official county seat of Grafton County.
North Haverhill is centered around the junction of New Hampshire Routes 10 and 116, on a bluff overlooking the Connecticut River, the western boundary of New Hampshire. It is situated in the middle of a fertile agricultural area at the western base of the White Mountains.

Route 116 heads east into the White Mountains, leading to the towns of Benton, Easton, and Franconia.
North Haverhill became the county seat of Grafton County when the county courthouse and related offices moved in 1972 from Woodsville into a new office complex on Route 10 just north of the North Haverhill village center.
