Alfonso d'Este (10 March 1527 - 1 November 1587) was an Italian nobleman.
Born at Ferrara, he was the illegitimate son of Alfonso I d'Este, Duke of Ferrara by his lover Laura Dianti. In 1523 his father gave him Montecchio Emilia and turned it into a feudal inheritance for cadet members of his family - in 1569 it was promoted to a marquessate by Maximilian II, Holy Roman Emperor.
Alfonso was legitimated in 1532 by cardinal Innocenzo Cybo and in 1533 by his father Alfonso I. His first marriage followed on 3 January 1549, to Giulia della Rovere, daughter of Francesco Maria I della Rovere, Duke of Urbino and Eleonora Gonzaga. In 1584 he married Violante Signa, though that marriage remained childless.
He died at Ferrara in 1587.
Alfonso had by Giulia della Rovere the following children:
