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). It ends at US 97 north of the Beebe Bridge on the Columbia River north of Chelan Falls. 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.

SR 150 begins at the intersection of Wapato Point Parkway and Wapato Way in the unincorporated community of Manson on the north shore of Lake Chelan. The highway travels southeast parallel to the shore of Lake Chelan into Chelan and turns south to serve Lakeshore Park. Within Chelan, SR 150 is routed east onto Johnson Avenue before turning south onto Saunders Street and intersecting US 97 Alternate and beginning a short concurrency as Woodin Avenue. US 97 Alternate splits off, traveling northeast, and SR 150 continues southeast towards Chelan Falls and crosses over the Cascade and Columbia River Railroad. The highway ends at an intersection with US 97 north of the Beebe Bridge on the Columbia River.
