New Hampshire Route 121 (abbreviated NH 121) is a 22.555-mile-long (36.299 km) north–south state highway in Rockingham and Hillsborough counties in southeastern New Hampshire. The road winds through the communities of Atkinson, Hampstead, Sandown, Derry, Chester, and Auburn. The southern terminus of NH 121 is at the Massachusetts state line in Plaistow, where the road, named Atkinson Depot Road, continues into the city of Haverhill as an unnumbered local road (North Main Street) leading to Route 125. The northern terminus is at a traffic circle, where NH 121 meets New Hampshire Route 28 Bypass (the Londonderry Turnpike) in eastern Manchester. At this point, the road is known as Manchester Road.
