Del Norte County is a county at the far northwest corner of the U.S. state of California, along the Pacific Ocean adjacent to the Oregon border. Its population is 27,743 as of the 2020 census, down from 28,610 from the 2010 census. The county seat and only incorporated city is Crescent City. Del Norte was pioneered and populated by Azorean Portuguese settlers and dairy farmers, which may account for the local pronunciation of the county name. Locals pronounce the county name as Del Nort, not Del Nor-teh as would be expected in Spanish.
