Route 2 is a 33.6-mile (54.1 km) state highway in Rhode Island, that runs from U.S. Route 1 in Charlestown to US 1 in Providence.

It then turns to the north and parallels Route 4 until reaching Interstate 95.

It continues through downtown Cranston and has interchanges with Route 37 and Route 10 before reaching its northern terminus at US 1 slightly inside the city line of Providence.

Route 2 is a heavily traveled highway in Cranston and Warwick as it is a major commercial corridor.

For a brief time during the construction of the Route 10 freeway, Route 2 left Reservoir Avenue in Cranston and turned north onto the current Route 10 freeway, ending at the Olneyville exit.
