Astolfo is a fictional character in the Matter of France where he is one of Charlemagne's paladins. He is the son of Otto, the King of England, and is a cousin to Orlando and Rinaldo, and a descendant of Charles Martel. While Astolfo's name appeared in the Old French chanson de geste The Four Sons of Aymon, his first major appearance was in the anonymous early fourteenth-century Franco-Italian epic poem La Prise de Pampelune. He was subsequently a major character in Italian Renaissance romance epics, such as Morgante by Luigi Pulci, Orlando Innamorato by Matteo Maria Boiardo, and Orlando Furioso by Ludovico Ariosto.
