Francesco Maria Scala (Naples, 1819 – Washington, D.C. 18 April 1903) also known as Francis M. Scala, was an Italian, naturalized American, military, band director and musician. He was the first and one of the most important and influential directors of United States Marine Corp (USMC) Band. He defined the instrumental organization that the band maintains, he was an extremely prolific musician and composer, and improved and enlarged the repertoire of the ensemble. It is thought that under his direction the USMC Band executed for the first time the melody "Potpourri-Fantasie" from the opera Geneviève de Brabant by Jacques Offenbach. This melody is now known as the Marines' Hymn.
