San Giovanni Battista de Rossi is a church on via Cesare Baronio in the quartiere Appio-Latino of Rome, Italy.

It is dedicated to Saint Giovanni Battista de' Rossi (1698–1764), who was canonized in 1881 by Pope Leo XIII.

[1][2] This church building was commissioned by Pope Pius XII in 1938 from the architect Tullio Rossi [it].

St John Baptist de Rossi's relics were translated here from the church of Santissima Trinità dei Pellegrini on 23 May 1965, his feast day, with Cardinal Luigi Traglia, the Vicar General of Rome, presiding.

[3] Nearly four years later, on 30 April 1969, Pope Paul VI made it a titular church.
