State Route 125 (SR 125) is a state highway in the U.S. state of Washington. It extends 23.65 miles (38.06 km) from OR 11 south of Walla Walla, north to State Route 124 west of Prescott. SR 125 passes U.S. Route 12 and Walla Walla. The route serves as a connector from US 12 to SR 124, Prescott, and Pendleton, Oregon (via OR 11).

SR 125 was established in 1964 after the 1964 highway renumbering, along its current route. Before SR 125 was established, the route from Oregon to Walla Walla was the Walla Walla branch of Primary State Highway 3 and the route from Walla Walla to Prescott was Secondary State Highway 3E. Even though SR 125 was established in 1964, no signs went up until the law that made SR 125 was approved by the Washington State Legislature in 1970. SR 125 also has a spur route that connects the highway with U.S. Route 12 eastbound towards Clarkston. The spur route is located entirely in Walla Walla.
