Chiesa di San Filippo Apostolo, Baroque church in Syracuse, Italy.

The Chiesa di San Filippo Apostolo is a baroque church in the Giudecca quarter of Ortigia, Syracuse, built between 1706 and 1742 to a design modelled on Rosario Gagliardi's church of San Domenico in Noto. Its interior was redecorated in neoclassical stucco after a bomb fell on the church on 10 July 1943, and the tall dome was demolished in July 1986 and later rebuilt in lighter materials.

The building was constructed during the 1700s and replaced a medieval synagogue that previously occupied this location. Its placement on this historic site reflects how the religious use of the area evolved over time.

The name recalls the Giudecca, the Jewish quarter where the church stands; scholars have suggested a synagogue once occupied this site, and the hypogeal rooms may have served as ritual baths. Since 1492 the Arciconfraternita di San Filippo has held the area, and the church was reopened for worship in June 2010 after restoration.

The church stands in the Giudecca quarter of Ortigia, a short walk from Piazza Duomo. It was closed to worship from 1968 until restoration work allowed reopening in June 2010, so check current access before setting out. The entrance lapide commemorating the 1926 works is worth a look on arrival.

The underground rooms are reached through a small surviving opening of the old San Filippo quarry, from which the Corinthians extracted fresh water; some scholars think the hypogeal rooms first served as purification baths for the synagogue, though this remains a hypothesis. A bomb fell on the church on 10 July 1943.
