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.

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.
