Lucius Clapp Memorial

The Lucius Clapp Memorial is a historic library building in Stoughton, Massachusetts. The single story masonry Renaissance Revival structure was built in 1903. It was Stoughton's first purpose-built library building, and was built on the site of its first schoolhouse. The building was designed by Walter Atherton and given to the town by Lucius Clapp, a local schoolteacher and businessman. It now houses the Stoughton Historical Society.

The building was listed on the National Register of Historic Places in 1992.
