Sacramento State University Library, Academic library in Sacramento, United States.

Sacramento State University Library is the main library of California State University Sacramento, located on the university campus in the eastern part of the city. It spans several floors with reading areas, group study rooms, computer stations, and access to a wide range of digital databases.

The library was founded in 1947 alongside Sacramento State College and started in temporary spaces on campus. Over the following decades, the collection grew steadily, leading to a dedicated building that could accommodate more resources and more users.

The Tsakopoulos Hellenic Collection, named after developer and alumnus Angelo Tsakopoulos, holds over 75,000 volumes, ephemera and artwork, making it the largest of its kind in the nation. The library also keeps the Japanese American Archival Collection, begun in 1994 with schoolteacher Mary Tsukamoto's donation on the wartime internment of Japanese Americans, and the Magnus Hirschfeld Collection of Gay, Lesbian, Bisexual and Transsexual History.

The library is open to all visitors, though some services are reserved for university students. Opening hours change depending on the academic calendar, so it is worth checking ahead of your visit.

The Sōkiku Nakatani tea room on the ground floor came from an anonymous donor honoring a late mother who practiced and taught chadō; the gift included her teaware and ceramics. Members of San Francisco's Uransenke Foundation perform the traditional ceremony on campus several times a year.
