Memorial Hall Library is the public library of Andover, Massachusetts. The building was built with Italianate styling in 1873 to a design by J. F. Eaton, a longtime associate of the Boston architect Gridley J. F. Bryant. Funding was provided by a number of leading local businessmen, and construction was by the firm of Abbott & Jenkins. It was designed to house the town library, which it still does, and to act as a memorial to the town's Civil War soldiers. It was renovated in the 1920s under the direction of architects Coolidge & Carlson, at which time it acquired its Colonial Revival details. Small additions were completed in 1961 and 1968. In 1988 a large addition, which doubled the size of the building, was completed. This was designed by Shepley, Bulfinch, Richardson & Abbott.
The building was listed on the National Register of Historic Places in 1982.
