Leonello d'Este (1407-1450) was marquis of Ferrara and Duke of Modena and Reggio Emilia from 1441 to 1450. He was one of the illegitimate sons of Niccolò III d'Este. In 1429 Niccolò obtained a papal sanction for Leonello's legitimisation and named him his heir.

Giovanni da Oriolo's portrait of Leonello may reflect a lost painting by Jacopo Bellini that was allegedly painted in 1441 in competition with Pisanello.
