Apollo Granforte (20 July 1886, Legnago – 11 June 1975, Milan) was an Italian opera singer and one of the leading baritones during the inter-war period of the 20th century.

At 9 o'clock on the morning of 22 July 1886, when Granforte was two days old, he was left in a basket at the Ospedale Civile in Legnano, wrapped and wearing a bonnet to which a brass medal was attached by white cotton thread.

At 16 he sang tenor in Lucia di Lammermoor, put on by a small company that traveled the countryside and performed in town squares.

There he was heard by a wealthy music lover named Pedro Valmagia (aka Pietro Balmaggia), who paid for him to study at the La Prensa Conservatory of Buenos Aires.

At the outbreak of World War I, Granforte and family returned to Italy sponsored by Valmagia, who had earlier helped the baritone begin his studies.

He then toured the war zone entertaining the Italian troops, alongside Alessandro Bonci and Elvira de Hidalgo.

Granforte possessed a big, rich, vibrant voice, quite similar in quality to that of Titta Ruffo, with a sinister undertone, and quickly established himself in the great baritone roles of Verdi and the verismo composers.

Among his pupils were soprano Leyla Gencer, bass Raffaele Arié, and tenors Flaviano Labò and Jesús Quiñones Ledesma.

Along with business partner Luigi Devizzi he owned the factory that produced these lamps, as well as a farm, both situated at a large villa in the Milan suburb of Gorgonzola, where he died on 11 June 1975.
