The Church of San Ferdinando is a historic church located on the Piazza Triesti e Trento, near the Royal Palace of Naples, in central Naples, Italy.
The original church at the site was dedicated by the Jesuits to St Francis Xavier, and was built in 1636. Reconstruction in mid 1650s was entrusted to Cosimo Fanzago. In 1767, with the expulsion of the Jesuits from the realm, the church was granted to the Padri Costantiniani who dedicated the church to St Ferdinand in honor of the Neapolitan King.
The counterfacade has a fresco with the story of St Francis Xavier and other Jesuits by Paolo De Matteis. The church contains statues by Domenico Antonio Vaccaro and Giuseppe Sanmartino. The main altarpiece is a canvas depicting San Ferdinando by Federico Maldarelli.
