Renzo da Ceri, true name Lorenzo dell'Anguillara (1475 or 1476 – January 1536) was an Italian condottiero.
Born in Ceri, a small village in Lazio (now part of Cerveteri), he was the son of Giovanni degli Anguillara.
He fought for the Orsini family against the Papal States and Cesare Borgia.
He defeated Silvio Savelli but was in turn beat by Prospero Colonna, whom he had harassed during the siege of Crema.
He led Clement VII's troops in his feudal war against the Colonna family and was present at the Sack of Rome (1527).
