The Oratorio dei Bianchi is a Baroque chapel or prayer room located on the Piazzeta dei Bianchi, about equidistant between the churches of Santa Maria dello Spasimo and Santa Teresa alla Kalsa in the quarter of the Kalsa, within the historic centre of Palermo, region of Sicily, Italy.

This peculiar oratory is composed of diverse components incongruently linked.

This ancient church was dedicated to the Virgin and contained the tag della Vittoria, because in the 11th-century, the Normans under Robert Guiscard had been able to enter the besieged Saracen city through a gate at this site.

The ground floor of the exterior is made from large stone blocks with masks sculpted in the arch keystones.

The interiors have a few stucco sculptures completed by Serpotta and his family, The main meeting room for the members was frescoed in 1776 by Gaspare Fumagalli in a neoclassical style.
