Yakima Ridge is a long anticline mountain ridge in Yakima County and Benton County in the U.S. state of Washington.

From its western end just north of the city of Yakima, the ridge runs east-southeast through the Yakima Training Center to its eastern end at Hanford Reach National Monument and the Hanford Site.

Yakima Ridge is part of the Yakima Fold Belt of east-tending long ridges formed by the folding of Miocene Columbia River basalt flows.
