Monterey County wine is a appellation that designates wine made from grapes grown in Monterey County, California which lies entirely within the expansive multi-county Central Coast viticultural area. County names in the United States automatically qualify as legal appellations of origin for wine produced from grapes grown in that county and do not require registration with the Alcohol and Tobacco Tax and Trade Bureau (TTB). TTB was created in January 2003, when the Bureau of Alcohol, Tobacco and Firearms, or ATF, was extensively reorganized under the provisions of the Homeland Security Act of 2002.

Chalone identifies the first American Viticultural Area (AVA) established in Monterey County, California straddling its border with San Benito County where it is the second established AVA. Chalone viticultural area is located in the Gabilan Mountains east of Soledad. It was recognized by the Bureau of Alcohol, Tobacco and Firearms (ATF) effective on July 14, 1982 after reviewing the petition submitted by the Gavilan Vineyards, Inc. to establish a viticultural area in Monterey and San Benito counties to be named "The Pinnacles." The area encompasses 8,640 acres (14 sq mi) and the proposed name was recognition of the nearby Chalone peaks.
