San Silvestro is a Romanesque-style, Roman Catholic parish church located at the intersection of Via dei Pellegrini #23 with Piazza del Gesu, in Viterbo, region of Lazio, Italy.
Atop the roofline are two Romanesque-era lions (Viterbese symbols) which were affiliated with the coat of arms of the Ghibelline Tignosi family.
From the late seventeenth century until 1825, the monks of the Penitenza took rooms in the nearby palace belonging to the Di Vico family, and used San Silvestro for their religious services.
In 2024, the church is assigned to the Catholic society of Knights and Dames of the Equestrian Order of the St Sepulcher.
