Sacro Cuore Immacolato di Maria (Sacred Immaculate Heart of Mary), is a titular church in Piazza Euclide, Rome. It was built by the architect Armando Brasini (1879–1965). Its construction began in 1923 with the design of a Greek cross inscribed in a circle with an articulated facade, and completed before 1936, the year in which it was made a parish church and granted to the Congregation of Missionary Sons of the Sacred Immaculate Heart of Mary, usually known as the Claretians.
