Blewett Pass, at an elevation of 4,124 feet, is a mountain pass in the Wenatchee Mountains of Washington state that is crossed by U.S. Route 97. Named for Edward Blewett, a Seattle mining promoter of the 1880s, it lies on the route of the historical Yellowstone Trail. Unlike the many well known passes that lie on the spine of the Cascades, Blewett Pass lies on the divide between the Wenatchee River to the north and the Yakima River to the south.
