The Hunt Memorial Library, also known as the John M. Hunt Memorial Building, is a historic former library building at 6 Main Street in downtown Nashua, New Hampshire. Built in 1903, it is a significant early work of the renowned Gothic Revival architect Ralph Adams Cram, then in partnership with Goodhue and Ferguson. It is a multi-level structure built of brick laid in Flemish bond, with limestone trim. Its three-story tower is an imposing presence at the upper end of Main Street. The Nashua Public Library moved to a new building in 1971. The building is owned by the city and is available for rent for functions.
