Soldiers' Memorial Library is a historic library building at the junction of Park Row and Union Street in Mansfield, Massachusetts. The 2-1/2 story Gothic Revival structure was designed by the noted firm of Peabody and Stearns, and built in 1899-1901. The building and land were primarily a gift from Elizabeth F. Noble. It was designed to house the public library on the ground floor, and provide a memorial to the town's American Civil War soldiers on the upper floor.
