Route 133 is an east–west Massachusetts state route that runs from Lowell to Gloucester.

Route 133 begins at the junction of Route 38 and Route 110 in Lowell, where Route 110 begins a concurrency with Route 38 northbound. Route 133 heads east from this point, heading through the northern end of Tewksbury, where it has a junction with I-495 at Exit 39. Shortly after crossing the highway, Route 133 enters Essex County and the town of Andover. In Andover, Route 133 crosses I-93 at Exit 43 and continues eastward, bypassing the town center to the north as it crosses Route 28 in Shawsheen Village.

From there, Route 133 continues eastward into the town of North Andover. In North Andover, Route 133 crosses Route 114 (the Salem Turnpike) just north of Merrimack College. It then joins Route 125 for a concurrency that lasts for 2.7 miles (4.3 km). The two routes split next to Lawrence Municipal Airport, with Route 133 passing the northern banks of Lake Cochichewick before entering Boxford. The route passes through the village of West Boxford before continuing into Georgetown.
