Enrico "Arrigo" d'Aragona (birth date unknown – 1478) was an illegitimate son of the King of Naples, Ferrante I of Aragon.
In May 1473 he was granted by his father the fief of Gerace, which recently had been freed from the dominion of the Caracciolo family and had become a state-owned city.
[4] He died after eating poisonous mushrooms in the Castle of Terranova da Sibari, where he had gone, as a guest of Marino Correale of Grotteria, to collect taxes for the King of Naples.
Other people died along with him, while his brother Cesare, Marquis of Santa Agata, who also ate the mushrooms, survived.
Five months later, in March 1499, his son, also called Alfonso, was born and immediately invested as the Marquis of Amalfi as his father's only heir, with Giovanna as Regent.
