Dundee Hills is an American Viticultural Area (AVA) located in Yamhill County, Oregon within the Willamette Valley AVA, and is located about approximately 28 miles (45 km) southwest of Portland, Oregon, and about 40 miles (64 km) inland from the Pacific Ocean near the town of Newberg.

It was established on November 30, 2004 by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury after reviewing a petition submitted from Alex Sokol Blosser, secretary of the North Willamette Valley AVA Group, proposing the establishment of the 6,490-acre "Red Hills" viticultural area in Yamhill County.

The soil is Jory series reddish silt, clay and loam, moderately fertile and well-drained suitable for grape cultivation.

The Chehalem Mountains to the north protect the region from the cool breezes that enter Willamette Valley from the Columbia Gorge.
