Santa Maria Assunta is a Roman Catholic parish church designed in 1661–1665 by Gianlorenzo Bernini; and located in the center of the town of Ariccia, Italy, where it stands across a piazza from the Palazzo Chigi Ariccia, once belonging to the family of Pope Alexander VII, Bernini's patrons in the construction of this church.

But interested in erecting a prominent church across from their palace in town, also undergoing restructuring by Bernini, the Chigi family commissioned the designs of Santa Maria Assunta from the architect.

Originally the portico cornice had the script stating Beatae Mariae Virgini Dei Matri in Caelum Assumptae (Blessed Mary Virgin Assumption as Heavenly Mother), along with a coat of arms of Pope Alexander VII.

The two flanking wings that encircle the church were built in 1771 under the patronage of Prince Sigismondo Chigi; they were not part of Bernini's design.

The cupola of the dome was decorated by Bernini's studio, but at the base the Angels that sustain the garlands were sculpted by Antonio Raggi.
