San Pietro in Montorio (English: "Saint Peter on the Golden Mountain") is a church in Rome, Italy, which includes in its courtyard the Tempietto, a small commemorative martyrium ('martyry') built by Donato Bramante.

Although there is no grave marker, tradition has it that Beatrice Cenci—executed in 1599 for the murder of her abusive father and made famous by Percy Bysshe Shelley, among others—is buried below the high altar.

The altarpiece is attributed to Giulio Mazzoni, while the funerary monument of Pope Julius III and Roberto Nobili are by Bartolomeo Ammannati.

The last chapel on the left contains a Baptism of Christ, attributed to Daniele da Volterra, and stucco-work and ceiling frescoes by Giulio Mazzoni.
