Livio Odescalchi (March 10, 1652 - September 8, 1713), Duke of Bracciano, Ceri and Sirmium, was an Italian nobleman of the Odescalchi family. Livio Odescalchi was born in Rome in 1655, the son of Carlo Odescalchi (1607-1673) and Beatrice Cusani. His paternal uncle was Benedetto Odescalchi, who was elected to the papacy as Pope Innocent XI in 1676. Since Innocent wanted to put an end to the established nepotism of the Curia, he did not make his nephew a cardinal, but instead granted Livio his own personal fortune of some forty thousand crowns, and conferred upon him his own title as Duke of Ceri in 1678. Livio was however eventually made Gonfaloniere and Captain General of the Church by his uncle.
