Teodorico Ranieri

Teodorico Ranieri of Orvieto (died 7 December 1306) was an Italian cardinal. He was archbishop of Pisa,^[1] and bishop of Palestrina.

In 1298 Ranieri was instrumental in the destruction of the city of Palestrina on the orders of Pope Boniface VIII, following the anti-papal revolt of the Colonna family. He was then made a cardinal^[2] in December of that year, and in 1300 until his death was the Camerlengo of the Holy Roman Church.

Ranieri came from an ecclesiastical family;^[1] his uncle was the bishop of Piacenza and his brother Zampo was bishop of Soana, and of Pietro.

The Palazzo Ranieri in Orvieto is named after a medieval tower once owned by Cardinal Ranieri.^[3]
