The Oratory of Gesù Pellegrino, also called the Oratorio dei Pretoni, is a Roman Catholic prayer hall or small church found on the corner of Via San Gallo and via degli Arazzieri in Florence, region of Tuscany, Italy.thumb|Facade
Formerly the church of San Salvatore, it belonged to the confraternity of that name, until in 1313 the bishop Antonio d’Orso instituted a hospice for pilgrim priests. The church was later dedicated to St James, and under the sainted Archbishop Antoninus, the confraternity set up a hospice for elderly priests.
In 1585 to 1588, commissioned by Alessandro de' Medici, restructuring was directed by Giovanni Antonio Dosio. In the interior are a fresco cycle and three altarpieces with episodes from The Life of Christ (1590) by the mannerist painter Giovanni Balducci. On the counterfacade is a recently restored organ. In the nave close to the entrance is the tomb of a famous parish priest, Arlotto Mainardi (1396–1484).
