State Route 528 (SR 528) is an east–west state highway in Snohomish County, Washington, located entirely within the city of Marysville. It travels 3.5 miles (5.6 km) from an interchange with Interstate 5 (I-5) in downtown Marysville to a junction with SR 9. The four-lane highway uses two local streets—4th Street and 64th Street—and primarily functions as a commuter route to the eastern outskirts of Marysville.

The corridor was added to the state highway system in 1963 as a branch of Primary State Highway 1 (PSH 1). During a highway renumbering the following year, this branch became SR 528; at the time, the highway was not yet complete and was only signed through downtown Marysville. SR 528 was completed in 1988 following the opening of a bridge over Allen Creek; in later years, the entire highway was expanded to four lanes.
