Multnomah County, County administrative region in Portland, United States
Multnomah County extends along the Columbia River in northwestern Oregon, encompassing Portland and several smaller municipalities across 466 square miles of territory.
The county establishment occurred on December 22, 1854, when local Portland business leaders requested separation from Washington and Clackamas counties due to administrative needs.
The name derives from the Chinook Native Americans who inhabited the lower Columbia River region and maintained fishing settlements along the waterways.
The county operates numerous public services through its headquarters in downtown Portland, including courts, libraries, health centers, and administrative offices.
Despite being Oregon's smallest county by land area, Multnomah contains the largest population concentration with over 815,000 residents recorded in 2020.
