San Basilio is the main Roman Catholic church, or chiesa madre (mother church), of the town of Regalbuto, province of Enna, region of Sicily, Italy.
The rich Baroque facade of the church clashes with the more sober and neoclassical square bell-tower to the right.
The church facade recalls the style of Rosario Gagliardi.
Unusual for churches in Sicily, the interior consists of a single nave with lateral chapels flanked by broad pilasters.
The apse has wooden choir stalls and is backed by a tall organ.
