The Church of Saint Athanasius (Italian: Sant’Atanasio, Latin: S. Athanasii), also known as Sant'Atanasio dei Greci, is a Roman Catholic titular church in Rome, built for use of a Greek College for the formation of Catholic clergy in the Eastern Rite, upon the formation of the Congregation of the Greeks by Pope Gregory XIII. In 1872 the church was entrusted to the Congregation for the Oriental Churches. On the 22 February 1962 Pope John XXIII granted it a titular church as a seat for Cardinals.
