San Francesco di Sales a Via Portuense is a mid 20th century subsidiary parish church at Via Portuense 524, in the south of the Gianicolense suburban district.
The dedication is to St Francis de Sales.
The church was built in 1950 to serve a school, the Istituto di San Francesco di Sales. (ISFS) This had been founded by the "Daughters of St Francis de Sales" in 1941, when construction work had begun on what was then a countryside site.
The architect was Tullio Rossi.
It is now a subsidiary church in the parish of Nostra Signora di Coromoto, but has its own priest.
A simple rectangular building with a pitched and tiled roof and exterior walls rendered in pale orange, it has a sanctuary as wide as the nave but with a lower roof. On the gable of the nave roof at its far end is a bellcote.
The façade is simple, with a wide V-shaped canopy occupying its entire width. Above this the wall is painted in an inverted V-stripe to match the canopy, the colour being a much paler orange. At the apex of this stripe is a round window, and the pale colour forms a wide border around it.

Weekdays 17:00 (18:00 in Daylight Saving Time);
