King's Highway 137, commonly referred to as Highway 137, is a provincially maintained highway in the Canadian province of Ontario that serves to connect the northern end of Interstate 81 in New York with Highway 401, via the Canadian span of the Thousand Islands Bridge. While this road connected to the international bridge when it opened in August 1938, it was not designated as a King's Highway until 1965.

The mainland section is a four-lane freeway with an interchange at the Thousand Islands Parkway in addition to its terminus at Highway 401. The section on Hill Island is a two-lane highway with limited development and two at-grade intersections. Connecting the two segments is the first bridge between the Ontario mainland and Hill Island, which is a toll bridge in the southbound direction (northbound tolls are paid on the New York mainland). The highway ends at the U.S. border, where it continues as I-81.
