Santa Maria Causa Nostrae Laetitiae is a 20th-century parochial church and titular church on the eastern edge of Rome. It is dedicated to the Virgin Mary, with the phrase causa nostræ lætitæ ("cause of our joy") being taken from the Litany of Loreto.

History

The church was built in 1939–41 in a Rococo style, to serve the workers at the Villaggio Breda weapons plant.

The historian Jean Coste was a priest at the church.

On 30 September 2023, Pope Francis made it a titular church to be held by a cardinal-priest.
