The Geneva Historical Society, a non-profit educational corporation, is committed to preserving and interpreting the collective heritage of Geneva, New York and its environs. Through its collections, educational programs, collaborations with other organizations, historic properties, and the Fund for Historic Geneva, the Geneva Historical Society preserves Geneva's past and cultivates an appreciation for Geneva history. Throughout its existence, the staff and supporters of the Geneva Historical Society have done much to collect and preserve information and material on the history of people, places, and events within the Geneva community.

The resulting collections encompass 1300 cubic feet of archives and 30,000 photographic images, as well as furniture, decorative art, costumes, textiles, fine art, tools and equipment, and four historic properties. The Geneva Historical Society consists of over 1,000 members in and around the community. The organization is committed to preserving and interpreting the rich culture and heritage of the diverse citizens who have made Geneva the city it is today. Over many years, the Society has been able to support its commitment to preservation through its Fund for Historic Geneva and its restoration efforts at the Prouty-Chew House, Rose Hill Mansion, and the John Johnston House.
