California State University, Chico is home to high-value programs, an active community, and engaging faculty who empower students to Do and Dare in their careers and lives. Better known as Chico State, we are a Hispanic-Serving Institution proud of our active and engaged student body and our strong connection with the local community and the state of California.

With a welcoming spirit and vibrant campus culture, we encourage students to discover their passions and advocate for what they care about through more than 100 degrees in undergraduate and graduate studies.

On March 12, 1887, a legislative act was enacted to create the Northern Branch of the California State Normal School. Less than a month later, Chico was chosen as the location. In 1887, General John Bidwell donated 8 acres (3.2 ha) of land from his cherry orchard. On July 4, 1888, the first cornerstone was laid. On September 3, 1889, doors opened for the 90 enrolled students. The library opened on January 11, 1890, with 350 books. On June 20, 1891, the first graduation took place, a class of 15.

In 1910, Annie Kennedy Bidwell donated an additional 2 acres (0.81 ha) of land to be used for work with elementary agriculture. The next year Mrs. Bidwell donated an orange orchard lot 55 × 440 feet (130 m) as the children's playground, which is connected to the Training School. Twenty years later in 1921, legislation was enacted to change the school's name to Chico State Teacher's College. In 1922, Chico State Teacher's College added a junior college curriculum and awarded a certificate after two years. Also in 1922, Bidwell Mansion was turned into a women's dormitory. In 1923 the first college paper, The Collegian, was published. In 1924, the state Board of Education allowed the school to grant baccalaureate degrees. Also in 1924, the wildcat was chosen as the mascot. In 1927 a gym was built on the grounds of Bidwell Mansion. In 1929, the cornerstone for the new administration building was laid on top of Normal Building's original cornerstone.

In 1935, Bidwell Hall was turned into a recreation and student center—the first student union. Also in 1935 a legislative act changed the college name from Chico State Teachers College to Chico State College. In 1937 evening classes started on campus and athletic fields were purchased from the Chico Board of Education.

In 1948, dorms for 500 male students were set up on west side of Warner Street. The buildings were built during World War II and were used as bachelor quarters for a Marine Hospital in Klamath Falls, Oregon.

In 1950, California's governor allowed state colleges to grant Master of Arts degrees. In 1951 the college reorganized from 18 departments into seven divisions with chairmen. Then in 1956 a new flagpost and sign in front of Kendall Hall was donated by the class of 1956. In the following year, 1957, a new cafeteria was built and the rose gardens were planted. In 1958 the first "telecourse" was taught, Psychology 51.

The Arts & Humanities Building is one of the newest buildings on campus. It opened in July 2016.
In 1972, Chico State College became California State University, Chico.

In 1975, broadcasts of classes through closed circuit TV were used for the first time by residents in Oroville, Marysville and Colusa.

In 1977, the other campus paper, The Wildcat, changed its name to Chico News and Review and moved off campus to become an independent publication. In 1978 bike riding was restricted on campus.

In 1987, Chico State was ranked as the top party school in the nation by Playboy.
