Goose Gap is the 19th American Viticultural Area (AVA) in Washington, United States. It encompasses the local region surrounding Goose Mountain in Benton County between Kiona to the west, and Richland along the Columbia River to the east. The viticultural area was formally established on August 2, 2021, by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury after reviewing the petition submitted by geologist/vintner, Alan Busacca, on behalf of the Goose Gap Wine Grower's Association, proposing the viticultural area "Goose Gap". The area is a sub-appellation entirely within the Yakima Valley and the expansive Columbia Valley AVAs sandwiched on a northwest–southeast axis between neighboring viticultural areas Red Mountain and the minute Candy Mountain.
