Route 110, is a southwest–northeast state highway in Massachusetts. The route travels from West Boylston in Central Massachusetts to Salisbury near the coast. Route 110 is paralleled by Interstate 495 for most of its length, and interchanges with the freeway several times along its journey.

Route 110 begins at Route 12 in West Boylston, just north of the Wachusett Reservoir and the border with Worcester. The route follows north of the reservoir, passing through Sterling before entering Clinton. In Clinton, Route 110 shares a quarter-mile concurrency with Route 62 and Route 70 before heading northward, crossing the Nashua River and passing through Lancaster.

The route continues into Bolton, crossing Route 117 and passing the Bolton Flats before entering the town of Harvard. Route 110 continues through the village of Still River, wrapping around Bare Hill Pond before joining Route 111, starting a 3.7-mile long concurrency which crosses Route 2 at Exit 38, just east of Fort Devens. The concurrency with Route 111 ends in Ayer in Middlesex County at a rotary junction with Route 2A, where Route 110 begins a concurrency with Route 2A eastward into Littleton.
