History

Denio was named after Aaron Denio, who settled in the area in 1885. He was born in 1824 in Illinois and traveled to California in 1860. He worked in milling, mining, and farming in Nevada and California for 25 years before settling near the Oregon-Nevada border. He died at Denio in 1907. The Denio post office was established in Oregon in 1888. After World War II a number of businesses relocated south of the state line to take advantage of Nevada’s lack of an income tax and more liberal liquor, gambling, and prostitution laws. The post office was moved and reopened in Nevada in 1950 for Nevada addresses, not Oregon.
