State Route 150 (SR 150) is a 11.76-mile (18.93 km) long state highway serving Chelan County in the U.S. state of Washington. The highway begins in the unincorporated community of Manson and travels southeast along the north shore of Lake Chelan into Chelan, where it is briefly concurrent with U.S. Route 97 Alternate (US 97 Alternate).

The road, which has existed since the 1890s, was signed as Secondary State Highway 10C (SSH 10C) and part of SSH 10D in 1937. SSH 10C became SR 151 and SSH 10D became SR 150 in the 1964 highway renumbering, the latter being renumbered in 1987 as part of US 97.
