Springdale is an unincorporated community in Multnomah County in the U.S. state of Oregon. Located between Troutdale and Corbett on the Historic Columbia River Highway, it was named for the many springs in the area. In the 1890s, the east end of the community was called Springdale, but the west end was called Gage. Gage had a post office from 1900 to 1903.
