Paso Robles is the third American Viticultural Area (AVA) located in San Luis Obispo (SLO) County, California.

The state's 29th AVA was established by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury on October 4, 1983 after reviewing the petition submitted by Martin Brothers Winery accompanied by 51 signatures of local grape-growers and wineries proposing a viticultural area named "Paso Robles.

This land grant includes the present areas of Paso Robles, Templeton, and Adelaida.

The community serving the hotel and resort visitors was incorporated as the City of El Paso de Robles on February 25, 1889.

In 1914, Ignacy Jan Paderewski, the famous Polish pianist, conductor, and statesman, established a vineyard on his ranch.

Wine produced by York Mountain Winery from this vineyard was awarded a gold medal at the California State Fair.
