Ciriaco Rocci (August 8, 1582 – September 25, 1651) was an Italian Catholic Cardinal and papal Apostolic Nuncio to Switzerland and Holy Roman Empire.
[1] In 1628 he was appointed Latin Archbishop of Patras, consecrated bishop on 2 July 1628 by Cardinal Giulio Cesare Sacchetti and sent to Switzerland by Pope Urban VIII as an Apostolic Nuncio.
That same year, Rocci came into possession of one part of the Villa Muti which had been divided upon the death of his uncle (on his mother's side) Cardinal Pompeo Arrigoni.
His elevation to cardinal was not revealed until 1633, prior to which he was appointed as nuncio to Holy Roman Empire.
[3] He participated in the Papal conclave of 1644 which elected Pope Innocent X and between 1646 and 1647 he was appointed Camerlengo of the Sacred College of Cardinals.
