The Willamette Valley is a 150-mile (240 km) long valley in Oregon, in the Pacific Northwest region of the United States. The Willamette River flows the entire length of the valley and is surrounded by mountains on three sides: the Cascade Range to the east, the Oregon Coast Range to the west, and the Calapooya Mountains to the south.

The valley is synonymous with the cultural and political heart of Oregon and is home to approximately 70 percent of its population including the five largest cities in the state: Portland, Eugene, Salem, Gresham, and Hillsboro.

The Willamette Valley is Oregon’s premier wine region, known for producing some of the world’s best Pinot Noir. It has over 700 wineries and is recognized as one of the top wine destinations globally. The valley’s fertile soil supports a diverse range of crops, including hops, hazelnuts, berries, and nursery plants, making it a key part of Oregon’s agricultural economy. Oregon produces nearly 99% of the nation’s hazelnuts, most of which come from the Willamette Valley. The region has a temperate oceanic climate, with warm, dry summers and cool, wet winters, making it ideal for both agriculture and outdoor activities. The valley was the final destination for many pioneers traveling the Oregon Trail in the 1800s. The region’s rich history includes early settlements, Native American heritage, and the development of Oregon’s statehood.

Beyond its vineyards, the valley offers hiking, cycling, and river activities. The Willamette River is popular for kayaking, paddleboarding, and fishing. The surrounding mountains also provide great opportunities for outdoor exploration. Home to major universities like the University of Oregon (Eugene) and Oregon State University (Corvallis), the region also boasts a thriving arts and music scene, museums, and cultural festivals.
