Route 137 is a main highway running north/south through the city of Stamford, Connecticut. It runs for about 9.3 miles (15.0 km) from Downtown Stamford to the New York state line in the town of Pound Ridge, New York.

Route 137 begins as a 4-lane/6-lane divided arterial road from US 1 in downtown Stamford, heading north to an interchange with Route 15/Merritt Parkway. The route then continues as a 2-lane road all the way to the New York state line in the town of Pound Ridge, New York. Past its south end at US 1, the roadway of Route 137 continues for another 0.3 miles (0.48 km) to I-95, designated as Special Service Road 493 (SSR 493).

The section of Route 137 from High Ridge Road to the state line is designated the Yankee Division Highway.

The route was commissioned in 1932 with the southern half running along a slightly different alignment than the current route. In the 1920s, this route had been known as State Highway 318. The original path of Route 137 consisted only of High Ridge Road. Its southern terminus was located at the intersection of Long Ridge Road (Route 104), Summer and Bedford Streets, also known as "Bull's Head", in Stamford. Since 1976, Route 137 follows High Ridge Road south onto Cold Springs Road and onto Washington Boulevard and ends at Tresser Boulevard (US 1) in front of the Stamford Government Center. Route 104, which originally extended south into downtown Stamford using Bedford and Summer Street, was cut back to end at its current southern terminus at the same time.
