Longfellow School (also known as Deniston School) at the corner of Monroe Street and McClure Avenue in Swissvale, Pennsylvania, was built in 1902. It was added to the National Register of Historic Places on June 28, 1984.
The building was in use as residential apartments until February 2012, when residents were evicted based on a determination by the Swissvale Fire Chief that the building had become uninhabitable.
