State Route 168 (SR 168) is a legislated, but not constructed, state highway located in Washington, United States. The highway is meant to serve as an alternate crossing through the Cascade Range at Naches Pass, supplementing the seasonal Chinook Pass on SR 410. Proposals were first drawn in the 1930s, and the highway has been codified in law under its current designation since 1970, but no construction has occurred.
