Antonio Carafa (died 10 October 1437/8), called Malizia ("the crafty"), was a nobleman and diplomat of the Kingdom of Naples. In the conflict between the Durazzo and Valois over the throne, he supported the Durazzo. He played a major role in the creation of the Aragonese claim to the throne and was a staunch supporter of King Alfonso V of Aragon until his death.
Carafa was born around the middle of the 14th century. His father was Giovannello Carafa and his mother Mariella Mariscalchi. He had three brothers: Niccolò, Tommaso and Gurrello. He married Caterina Farafalla and had seven sons and two daughters: Carlo, Francesco, Tommaso, Antonio, Gurrello, Giovanni Battista, Diomede, Caterina and Diana. Cardinal Oliviero Carafa and Archbishop Alessandro Carafa were sons of Francesco.
In 1384, with his brother Gurrello, Carafa fought for King Charles III against a challenger to the throne, Duke Louis I of Anjou. On 20 December 1392, he was part of the council that declared Charles's successor, Ladislaus, to be of age. On 15 October 1394, he took part in a council convoked by Ladislaus to affirm the kingdom's support for Pope Boniface IX during the Western Schism.
In 1400, Ladislaus appointed Carafa justiciar of the province of Bari and granted him an annual pension from the customs revenue of the port of Bari. That year, he purchased land in from the Countess Covella Gesualdo. In 1410, he and a cousin purchased the fiefs of Pescolanciano, Boccalino and Vignali with royal permission. In 1415, Queen Joan II confirmed his pension in Bari and appointed him captain of the territory of Montecassino. In 1417, she appointed him justiciar of the . In 1419, Carafa purchased the casali of Cupuli and Casacellola from the count of Caiazzo. In 1420, he was named castellan of Torre del Greco.
In April 1420, Carafa was part of a Neapolitan embassy to Pope Martin V, who supported the claim of Duke Louis III of Anjou to the throne. They travelled by sea to Pisa and met the pope in Florence. There, Carafa opened negotiations with the Aragonese ambassador, García Aznar de Añón. Returning to Naples without papal permission, he informed the queen and of the possibility of an alliance with Aragon and was sent to Sardinia to meet with Alfonso V. He arrived during the siege of Bonifacio. Alfonso accepted the offer to become Joan's adopted heir and in return defend Naples from Louis. Later accounts emphasise the skill and persuasiveness of Carafa's appeal to Alfonso to come the aid of a lady in peril. On 6 August 1420 at Alghero, Alfonso granted Carafa an annual pension for his services. Carafa was present on 5 September, when Alfonso's ambassadors formalized the adoption in Naples.
On 1 April 1422, Carafa received the fief of Vico di Pantano from Joan. He was also by then a royal seneschal and household knight. That same year, Alfonso ceded him the revenues of the gabelle of the bailliage of Manco at Cosenza and the customs of the port of San Lucido. In 1423, Joan granted him the tax revenues of Vico di Pantano. In the fall of 1423, when the conflict between Joan and Alfonso spilled out into the open and she renounced the adoption, Carafa sided with Alfonso. When Alfonso opted to return to Spain, Carafa sent his son Diomede and his nephew Caraffello with him. In July 1424, when an Aragonese fleet arrived in Naples to support Alfonso's brother Peter, Carafa engineered riots in favour of the Aragonese. After the queen's victory, he fled to Sessa Aurunca.
Carafa never abandoned the Aragonese cause. Joan died in 1435 and Alfonso immediately contested the succession with René of Anjou. Carafa died on 10 October 1437 or 1438 and was buried in San Domenico Maggiore. In his testament, he encouraged his relatives to be faithful to the cause he had supported.
A monumental tomb was built for Carafa between the 1440s and 1480s, probably by the workshop of on the orders of his son Diomede. An inscription commemorates its construction and celebrates Carafa as the man responsible for bringing Alfonso to Italy:
