Warren Creek Falls was a waterfall in Starvation Creek State Park on the north side of the Columbia River Gorge in Oregon, in a short highway corridor known for several nearby falls. Formed about 13,000 years ago by the Missoula Floods, it stood in a forested area off the western side of Viento Ridge in the Columbia Plateau. In 1938, Warren Creek was diverted through a tunnel to protect the newly built Columbia River Highway from washouts. The diversion ended the natural waterfall and created Hole-in-the-Wall Falls downstream, often confused with it. The original site remains beside the trail and briefly flows again when enough water spills over the tunnel crest.
