Alfonso Gesualdo di Conza (20 October 1540 – 14 February 1603) was an Italian Cardinal starting in 1561. He was from Calitri, not far from Naples. His attendance at the papal conclave of 1565-1566 at the age of only 25 makes him one of the youngest Cardinals ever to participate in a papal election.^[1]

He was Archbishop of Conza in 1564 (consecrated 23 April 1564 by Francesco Pisani), Bishop of Albano in 1583, Bishop of Frascati in 1587, Bishop of Porto e Santa Rufina in 1589, Bishop of Ostia in 1591, and Archbishop of Naples in 1596.

He was a patron of Sant'Andrea della Valle in Rome, the mother church of the Theatine Order.^[2] The composer Carlo Gesualdo was his nephew.
