San Salvatore in Primicerio, Catholic church in central Rome, Italy.

San Salvatore in Primicerio was a Catholic church in Rome's Ponte district, at the corner of today's Via dei Tre Archi and Vicolo di San Trifone, near Piazza Fiammetta. It had a single nave with a high altar and two side altars. It was demolished in 1934 to make way for a housing complex; its portal survives at Vicolo di San Trifone 1, inscribed EC(CLESI)A PAR(ROCHIALIS) S(ANCTISSIMI) SALVATORIS PRIMICERII.

San Salvatore in Primicerio was consecrated in 1113 by Leo Marsicanus, bishop of Ostia, during the pontificate of Paschal II. In the 15th century the abbot of San Paolo fuori le Mura granted it the revenues of Santo Stefano di Sutri, since its own income could not support its priests. Granted in 1604 to the Confraternity of Saints Trifone and Camillo, it was restored in 1676 and demolished in 1934 for a housing complex.

The name Primicerio came from the high Roman Church office on which the church depended, and the primicerius's insignia decorated its facade. Popular names included San Salvatorello, for its small size, and San Salvatore alla Volpe, after a nearby alley. From 1604 it was also called San Trifone, after the confraternity that moved here.

The church was demolished in 1934; its surviving portal stands at Vicolo di San Trifone 1, at the corner with Via dei Tre Archi, near Piazza Fiammetta. Look above the entrance for the inscription naming the parish church of the Most Holy Saviour of the Primicerio. The fresco and tombstones from the church are kept at the Pio Sodalizio dei Piceni by San Salvatore in Lauro.

The church's portal survives at Vicolo di San Trifone 1, inscribed EC(CLESI)A PAR(ROCHIALIS) S(ANCTISSIMI) SALVATORIS PRIMICERII.
