Washington Pass (el. 5477 ft./1669 m.) and Rainy Pass (el. 4875 ft./1486 m.) are two mountain passes on State Route 20 (North Cascades Highway) in the North Cascades mountains of Washington State. Rainy Pass is about 4 miles to the west of Washington Pass. The passes are typically closed between November and April due to heavy snowfall.

The north-south Pacific Crest Trail crosses east-west Highway 20 at Rainy Pass.
