State Route 204 (SR 204) is a short state highway in Snohomish County, Washington, United States. It connects U.S. Route 2 (US 2) at the eastern end of the Hewitt Avenue Trestle to the city of Lake Stevens, terminating at a junction with SR 9. The highway runs for a total length of 2.4 miles (3.9 km) and passes through several suburban neighborhoods.

The Everett–Lake Stevens road was originally added to the state highway system in 1937 as part of Secondary State Highway 15A (SSH 15A), which continued northeasterly to Granite Falls. The modern highway was built in 1954 and designated as SR 204 a decade later during the 1964 state highway renumbering, while the eastern half of SSH 15A became SR 92. Since then, suburban development in the area has necessitated planning for the reconstruction of the SR 9 intersection into a full interchange.
