Pietro Ghetti (died c. 1726, Naples) was an Italian sculptor. Born in Carrara of Roman descent sometime in the 17th century, he trained in Bernini's workshop and often collaborated with his brother Bartolomeo as well as working independently. Scholar believe that Bartolomeo usually worked on ornament whilst Pietro usually worked on sculpting the figures.
He is documented as working in Naples from 1671 onwards, having followed Bernini's architect and sculptor brother Luigi to the city.
