New Hampshire Route 125 (abbreviated NH 125) is a 51.994-mile-long (83.676 km) north–south state highway in Rockingham and Strafford counties in southeastern New Hampshire. It runs from Plaistow to just north of Milton. Although most of the road consists of only two lanes, NH 125 is a major north–south highway with heavy truck and tourist traffic, especially in the summer months, when the road is used as an alternate route between Interstate 495 in Haverhill, Massachusetts and the Spaulding Turnpike in Rochester.

The northern terminus of NH 125 is in the village of Union (town of Wakefield) at New Hampshire Route 16, just beyond 125's junction with NH 153. The southern terminus is in Plaistow at the Massachusetts state line, where the road continues southward as MA Route 125.

In the Rochester-Milton area, the road parallels the Spaulding Turnpike and is known as Milton Road in Rochester and White Mountain Highway in Milton. The Epping-Lee-Barrington section is known as the Calef Highway, named after Senator Austin L. Calef who owned the locally famous Calef's Store in Barrington.

The road between Epping and East Barrington (the intersection of Route 125 and Route 9) was built on the grade of the Boston and Maine Railroad's Worcester, Nashua and Portland Division, opened by the Nashua and Rochester Railroad in 1876.

Route description

Then it crosses Route 101 at exit 7. After that, it crosses US 4. Then it closely follows Route 16 and parallels the Maine border, until it ends at Routes 153 and 16 in Wakefield.
