Horse Heaven Hills is an American Viticultural Area (AVA) in southeastern Washington lying in portions of Klickitat, Yakima, and Benton counties, north and west of the Columbia River and south of the Yakima Valley and lies within the vast Columbia Valley appellation.

Horse Heaven Hills was established by the Alcohol and Tobacco Tax and Trade Bureau {TTB), Treasury on June 30, 2005 after reviewing the petition filed by Paul D. Lucas on behalf of regional wine grape growers.

Horse Heaven Hills borders the Yakima Valley AVA to the north and the Columbia River to the south.
