San Dalmazzo is a Roman Catholic church on via Garibaldi, in central Turin, region of Piedmont, Italy.

Adjacent to the church is the former convent and school of the Barnabite order.

From 1271 to 1606, the church had been linked to the Order of Canons Regular of Sant'Antonio of Vienne, but then was transferred along with the convent to the Barnabites.

[1] Between 1629 and 1631 the chapel of the Madonna of Loreto was built, imitating the Casa Santa (Holy House), which contains an icon related to Marian Apparitions.

In 1271 the church was entrusted to the Hospital Brothers of St. Anthony, that supported it until 1606, when passed, with the joined convent, to Barnabites.
