Maria Santissima Assunta in Cielo, Neoclassical Catholic church in Gela, Italy.

Maria Santissima Assunta in Cielo is a Latin-cross basilica on Piazza Umberto I, built from 1766 to 1799 and finished with a sandstone neoclassical facade in 1844. Two orders of columns, Doric below and Ionic above, frame a triangular pediment with a Marian emblem; a hemispherical dome on an octagonal drum rises over the crossing.

The present church replaced the 13th–14th-century Santa Maria de Platea, itself built over a Greek temple of the 6th–5th century BC probably dedicated to Hera. After the 1693 Val di Noto earthquake damaged the bell tower, construction of the new building began on 23 January 1766 and ended in 1799. The bell tower was added in 1837 to a design by Emanuele Di Bartolo, and the neoclassical sandstone facade by Giuseppe Di Bartolo Morselli was completed in 1844.

Locals call it 'a Matrici', the mother church, and it holds the Byzantine icon of Maria Santissima dell'Alemanna, patron of Gela. On Good Friday the statues of the Cristo Morto and the Addolorata are carried through the streets in procession.

The church faces Piazza Umberto I, with the main entrance up a flight of steps from the square. The south side has a single doorway; the north side, which also holds the bell tower and the parish house, opens onto a small garden. The 2025 restoration cleaned the sandstone facade and returned the doorways to their original dark green.

The organ above the main entrance has 31 pipes and was donated by Benito Mussolini after his visit to Gela on 14 August 1937, at the request of parish priest Antonino Li Destri. It was built in 1939.
