Camillo di Pietro J.U.D. was an Italian Cardinal of the Roman Catholic Church and both Camerlengo of the Sacred College of Cardinals and later Camerlengo of the Holy Roman Church.

The Camerlengo of the Holy Roman Church is an office of the papal household that administers the property and revenues of the Holy See. Formerly, his responsibilities included the fiscal administration of the Patrimony of Saint Peter. As regulated in the apostolic constitution Pastor bonus of 1988, the Camerlengo is always a cardinal, though this was not the case prior to the 15th century. His heraldic arms are ornamented with two keys – one gold, one silver – in saltire, surmounted by an ombrellino, a canopy or umbrella of alternating red and yellow stripes. These also form part of the coat of arms of the Holy See during a papal interregnum. The Camerlengo has been Kevin Farrell since his appointment by Pope Francis on 14 February 2019. The Vice Camerlengo has been Archbishop Ilson de Jesus Montanari since 1 May 2020.
