Stampede Pass is a mountain pass in the northwest United States, through the Cascade Range in Washington. Southeast of Seattle and east of Tacoma, its importance to transportation lies almost entirely with railroading, as no paved roads cross it. It is approximately twelve miles (20 km) south-southeast of Snoqualmie Pass, the gap for Interstate 90, and two miles (3 km) south of Keechelus Lake.

Interstate 90 (I-90), designated as the American Veterans Memorial Highway, is a transcontinental Interstate Highway that runs from Seattle, Washington, to Boston, Massachusetts. It crosses Washington state from west to east, traveling 298 miles (480 km) from Seattle across the Cascade Mountains and into Eastern Washington, reaching the Idaho state line east of Spokane. I-90 intersects several of the state's other major highways, including I-5 in Seattle, I-82 and U.S. Route 97 (US 97) near Ellensburg, and US 395 and US 2 in Spokane.
