Graton is an unincorporated town and census-designated place (CDP) in west Sonoma County, California, United States.

[3] The town of Graton is roughly 20 miles (32 km) from the California coastline.

[4] Graton's agriculture was historically concentrated on apple farming, but like most of rural Sonoma County it now focuses on wine production.

[6] Graton is located at the southeastern end of Green Valley, on the east bank of the seasonally flooding Atascadero Creek.

Graton is noted as lying at the approximate furthest southern and eastern extent of Russian colonization of the Americas.

These farms or ranches were used for producing additional food and for agricultural projects conducted by Fort Ross's agronomist Yegor Chernykh.

In 1836, a farm was established along Purrington Creek, between what are now the towns of Occidental and Graton.

There Chernykh erected barracks and five other structures, and grew vegetables, fruit, wheat, and other grains.

Chernykh also developed a large vineyard, introducing what has since become a major crop in the area.

[7] This region experiences warm (but not hot) and dry summers, with no average monthly temperatures above 71.6 °F (22.0 °C).

There were 723 housing units at an average density of 457.8 per square mile (176.8/km2), of which 72.2% were owner-occupied and 27.8% were occupied by renters.
