Antonello da Caserta, also Anthonello de Casetta, Antonellus Marot, was an Italian composer of the medieval era, active in the late 14th and early 15th centuries.
Earlier in the 20th century, Nino Pirrotta thought Caserta was a Neapolitan composer, but because most of his surviving works are in northern Italian manuscripts, this is now doubted (Günther and Stone 2001).
Allusions in his texts suggest that he worked for the Visconti family in Milan around the turn of the 15th century (Nádas and Ziino 1990), and a "frater Antoniello de Caserta" mentioned in an archival document may indicate that he was at the Visconti court in Pavia in 1402 (Günther and Stone 2001).
Antonello da Caserta is one of the more renowned composers of the generation after Guillaume de Machaut.
One of his ballades quotes Jehan Vaillant, a composer active in Paris.
