Hawaii State Public Library System, Cultural institution in Honolulu, United States.

The Hawaii State Public Library System is a network of 51 branches spread across six Hawaiian islands, providing books, digital resources, and educational materials to local residents. The facilities offer free access to online classes, language learning programs, and various streaming services.

The Honolulu Library and Reading Room Association, formed in 1879 and backed by King Kalākaua and Queen Emma, handed its 20,000 volumes to the Library of Hawaii trustees in 1909. A $100,000 Carnegie grant plus $27,000 from the territorial legislature funded the Hawaii State Library, whose cornerstone was laid on October 21, 1911; it opened February 1, 1913. C.W. Dickey added two wings in 1927, and the building joined the National Register of Historic Places in 1978.

The system's name comes from the Hawaiian-language spelling Hawaiʻi, with the ʻokina between the i and the i. Its founding collection grew from 20,000 printed materials donated in 1909 by the Honolulu Library and Reading Room Association, which had been supported by King Kalākaua, Queen Emma and Princess Bernice Pauahi Bishop.

Visitors can use the collections for free at branch locations on different islands or access digital resources from home. It helps to check in advance which services are available at your nearest location.

The system is the only statewide public library network in the United States, with 51 libraries on six islands and a collection of more than three million items. One branch on Oʻahu serves blind and print-disabled readers. Its head, the State Librarian, reports to the Hawaii Board of Education.
