Alfredo Napoleão dos Santos (Porto, 31 January 1852 — Lisbon, 20 November 1917) was the youngest of three Napoleão siblings, the others being Arthur Napoleão (1843–1925), and Aníbal Napoleão (1845–1880). All the three were pianists and composers. In 1869 he gave his debut recital in Rio de Janeiro, with great success. He made an extensive tour through the country and settled in Buenos Aires, and then in Montevideo, where he taught piano. In 1879 he was again in Rio de Janeiro and for some years toured the northern parts of Brazil. At that time he was at the height of his fame.
