The mission of the Riverhead Free Library is to provide the diverse community it serves with access to ideas, information, and a variety of educational, cultural, recreational, and intellectual resources. The Library will do so in an inviting, accessible, and eco-conscious manner.

The Riverhead Library began as a subscription Library in the 1870’s, and was chartered in 1896 by New York State. The Library existed for many years in the Savings Bank Building, various storefronts and the Roanoke Avenue School, until the land at 330 Court Street was donated by the Perkins family. The Library moved into its new home in 1964, going through two expansions to make it into the building we know today.

The Library is chartered to serve the 41,000+ residents of the Riverhead Central School District, comprising Riverhead, Aquebogue, Jamesport, South Jamesport, Northville, Baiting Hollow, Calverton, Flanders and parts of Wading River and Hampton Bays. In addition, the Library contracts with residents of East Quogue, Eastport/South Manor, Remsenburg/Speonk and East Moriches.

The Library is governed by a nine-member Board of Trustees. The Board of Trustees meets on the second Wednesday of the month at 6:30 pm. Members of the public are welcome to attend.
