State Route 220 (SR 220) was a 27.42-mile (44.13 km) long state highway located entirely in the Yakama Indian Reservation, Yakima County, Washington, United States. The highway linked Fort Simcoe State Park in the west to White Swan and Toppenish in the east. The highway had been built sometime between 1915 and 1937, and was renumbered from Secondary State Highway 3B during the 1964 state highway renumbering. The route was slated to be removed from the state highway system during the 1991 legislative session, and was removed April 1, 1992.

SR 220 started at Fort Simcoe State Park, headed easterly along Fort Simcoe Road until it intersected Hawk Road. At the t intersection with Hawk Road, the highway turned north and follows Hawk Road until an intersection with White Swan Road. The highway turned back east along White Swan Road, passing through downtown White Swan, before turning south along Curtis Street. The highway passed over a BNSF Railway rail line, formerly part of the Toppenish, Simcoe & Western Railroad, before Curtis street turned easterly and became Fort Road. Fort Road continued almost perfectly east for about 18 mi (29 km) before intersecting US Route 97 (US 97). After crossing US 97, the highway continued as a city street through west Toppenish before terminating at SR 22.
