San Giuseppe dei Teatini is a Roman Catholic church on via Vittorio Emanuele, at the southwest corner of the Quattro Canti, in the historic center of the city of Palermo, region of Sicily, Italy.

The church was built at the beginning of the 17th century by Giacomo Besio, a Genoese member of the Theatine order.

The interior has a Latin cross plan with a nave and two aisles, divided by marble columns of variable height.

The inner decoration is a nearly overwhelming parade of Baroque art, with stuccoes by Paolo Corso and Giuseppe Serpotta.

Frescoes decorate the nave ceiling and the transept vault, painted by Filippo Tancredi, Guglielmo Borremans and Giuseppe Velasquez.
