Fresno ( ; Spanish for 'Ash') is a major city in the San Joaquin Valley of California, United States. It is the county seat of Fresno County and the largest city in the greater Central Valley region. It covers about 115 square miles (300 km2) and had a population of 542,107 as of the 2020 Census, making it the fifth-most populous city, in California, the most populous inland city in California, and the 34th-most populous city in the nation. Named for the abundant ash trees lining the San Joaquin River, Fresno was founded in 1872 as a railway station of the Central Pacific Railroad before it was incorporated in 1885. It has since become an economic hub of Fresno County and the San Joaquin Valley, with much of the surrounding areas in the Metropolitan Fresno region predominantly tied to large-scale agricultural production.
