The Interurban Trail is a rail trail in King County, Washington.
It is a partially paved 14-mile (23 km) recreational trail open for non-motorized use. It connects Tukwila to Pacific, and the towns of Kent, Auburn, and Algona along the way.
The trail occupies an abandoned Puget Sound Electric Railway corridor and connects to the Green River Trail.
When completed, the trail will extend south through Pacific, across the county line into Sumner and Puyallup where it will connect with the Pierce County Foothills Trail and the planned Edgewood/Milton Interurban Trail.
