Santa Caterina d'Alessandria or Saint Catherine of Alexandria is a Roman Catholic church with a main facade on Piazza Bellini, and a lateral Western facade facing the elaborate Fontana Pretoria, in the historic quarter of Kalsa in the city of Palermo, region of Sicily, Italy. In front of the main facade, across the piazza Bellini, rise the older churches of San Cataldo and Santa Maria dell'Ammiraglio (or the Martorana), while across Piazza Pretoria is the Theatine church of San Giuseppe and the entrance to the Quattro Canti. Refurbished over the centuries, the church retains elements and decorations from the Renaissance, Baroque, and late-Baroque (Rococo) eras. This church is distinct from the Oratorio di Santa Caterina found in the Olivella neighborhood.
