The church of San Gregorio Barbarigo is a place of Catholic worship in Rome, located in the EUR district on Via delle Montagne Rocciose.
The church of San Gregorio Barbarigo was built between 1970 and 1972 by architect Giuseppe Vaccaro as the parish home. The latter was established January 28, 1964 with the decree of the Cardinal Vicar Clemente Micara Qua celeritate. Since 1973 the church is the seat of the cardinal's title of "San Gregorio Barbarigo alle Tre Fontane".
The church is dedicated to the Venetian saint Gregorio Barbarigo (1625–1697). He was cardinal and bishop of Padua, where he worked tirelessly for the implementation of the Council of Trent reform.
