New Hampshire Route 108 is a 42.430-mile-long (68.284 km) north–south state highway in Rockingham and Strafford counties in southeastern New Hampshire. The southern terminus of NH 108 is at the Massachusetts state line in Plaistow. The northern terminus is at an intersection with New Hampshire Route 125 and New Hampshire Route 202A in downtown Rochester.

At its southern end, NH 108 connects to Massachusetts Route 108, a very short state route which continues south for 0.91 miles (1.46 km) to Massachusetts Route 110 in Haverhill.^[2]

NH 108 is notable in being one of two routes (the other being New Hampshire Route 9) to intersect both U.S. Route 4 and New Hampshire Route 4 (a rare case of two completely separate routes in one state having the same number).
