The name Conconully comes from the Okanogan name for Salmon Creek, /qʷúnqʷunɬp/, which flows from Conconully to the Okanogan River at Okanogan. According to historian Harry M. Majors, the word means "cloudy". Originally named Salmon City after the nearby Salmon Creek, Conconully began as a gold miners camp, and served as the county seat from 1888 to 1914. It was officially incorporated on November 11, 1908.
