Map - Chico, California (Chico)

Chico (Spanish for "little") is the most populous city in Butte County, California, United States. Located in the Sacramento Valley region of Northern California, the city had a population of 101,475 in the 2020 census, reflecting an increase from 86,187 in the 2010 Census. Chico is the cultural and economic center of the northern Sacramento Valley, as well as the largest city in California north of the capital city of Sacramento. The city is known as a college town, as the home of California State University, Chico, and for Bidwell Park, one of the largest urban parks in the world.

The first known inhabitants of the area now known as Chico—a Spanish word meaning "little" —were the Mechoopda Maidu Native Americans.

The City of Chico was founded in 1860 by John Bidwell, a member of one of the first wagon trains to reach California in 1843. During the American Civil War, Camp Bidwell (named for John Bidwell, by then a brigadier general of the California Militia), was established a mile outside Chico, by Lt. Col. A. E. Hooker with a company of cavalry and two of infantry, on August 26, 1863.

By early 1865 it was being referred to as Camp Chico when a post called Camp Bidwell was established in northeast California, later to be Fort Bidwell. The city became incorporated January 8, 1872.

Chico was home to a significant Chinese American community when it was first incorporated, but arsonists burned Chico's Chinatown in February 1886, driving Chinese Americans out of town.

Historian W.H. "Old Hutch" Hutchinson identified five events as the most seminal in Chico history. They included the arrival of John Bidwell in 1850, the arrival of the California and Oregon Railroad in 1870, the establishment in 1887 of the Northern Branch of the State Normal School, which later became California State University, Chico (Chico State), the purchase of the Sierra Lumber Company by the Diamond Match Company in 1900, and the development of the Army Air Base, which is now the Chico Municipal Airport.

Several other significant events have unfolded in Chico more recently. These include the construction and relocation of Route 99E through town in the early 1960s, the founding of Sierra Nevada Brewing Company in 1979—what would become one of the top breweries in the nation —and the establishment of a "Green Line" on the western city limits as protection of agricultural lands.
