The William H. Long Memorial is a historic memorial building on Main Street in Hopkinton, New Hampshire. The brick, granite, and sandstone three-story building was constructed in 1890 as a memorial to a member of a prominent local family. The bequest stipulated that the building be used as a home for the local historical society, a function it continues to perform. It was also used to house the local public library. The building was designed by the Boston firm of Means & Gilbert, and is predominantly made of brick. The main entry, centered on the long wall, is recessed under a pilastered entablature topped by a semicircular tablet inscribed with the memorial inscription. Windows on the second floor are framed in ornamented stonework and topped by small oval oculus-like windows.^[2]

The building was listed on the National Register of Historic Places in 1977.^[1]
