Union County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 26,196. Its county seat is La Grande.

Union County comprises the La Grande, OR Micropolitan Statistical Area. It is one of the eight counties of eastern Oregon.

History

According to Oregon Geographic Names, the county is named for the town of Union. Union County was originally part of Baker County (which was originally a part of Wasco County, which was originally part of Clackamas County). The northern end of the Grande Ronde Valley was the first part to be settled. During the 1860s, population growth in eastern Oregon prompted the State Legislature to split Umatilla and Baker Counties from Wasco County in 1862. Further settlement in the Grande Ronde Valley led to the division of Baker County to create Union County on October 14, 1864. The county doubled in population between 1880 and 1890.

The choice of a county seat resulted in competition, based on geography and on economic and population growth, between La Grande and the city of Union. The county seat alternated between Union and La Grande until it permanently came to rest at La Grande in 1905. Between 1875 and 1913, adjustments were made between Union County's borders and the borders of Baker, Umatilla, and Wallowa counties.

In the 2016 presidential election, 65 percent of Union County voters voted for Republican Donald Trump, while 25 percent voted for Democrat Hillary Clinton and 10 percent of voters either voted for a Third Party candidate or wrote in a candidate.

Economy
The initial economic interest in Union County was mining, but most of the mines in the area were annexed by Baker County in 1901. The local economy continues to be based on natural resources, including farming (wheat, fruit, vegetables, mint, and grass seed), ranching (cattle and sheep), and timber. The ridges of Pyles Canyon are the site of the Elkhorn Valley Wind Farm, owned and operated by Horizon Wind Energy and whose power is sold to Idaho Power.  Since October 2010, the county board of commissioners has supported a "strategic investment program" for another wind power project in Oregon, Horizon Wind Energy's proposed Antelope Ridge Wind Farm; after delays due to concerns about the project's impact on wildlife,  the project has received support from Oregon Department of Fish and Wildlife.

Nearby mountains and streams offer hunting, fishing, skiing, and camping, all of which attract vacationers. Attractions include the Anthony Lakes (and its ski area), Minam River, Mount Emily, Blue Mountains, Umatilla National Forest, Wallowa–Whitman National Forest (including Eagle Cap Wilderness), Catherine Creek State Park, Hilgard Junction State Recreation Area, Thief Valley Reservoir, Cove Hot Springs Pool, the Hot Lake Hotel (first built in the 1860s due to nearby hot springs), and the Eagle Cap Excursion Train.
