The county of Fresno was formed in 1856 after the California Gold Rush. It was named for the abundant ash trees lining the San Joaquin River.

County residents voted to move the county seat from Millerton to Fresno. When the Friant Dam was completed in 1944, the site of Millerton became inundated by the waters of Millerton Lake. In extreme droughts, when the reservoir shrinks, ruins of the original county seat can still be seen.
