Marcus Livius Salinator (254 – c. 191 BC) was a Roman general and politician who fought in the Second Punic War, most notably during the Battle of the Metaurus.
After leading a successful campaign against the Illyrians, he was charged with malfeasance concerning war spoils during a mission to Carthage and was tried and found guilty on his return to Rome.
In 207 BC, during the Second Punic War, he was again elected consul (supposedly against his wishes) with Gaius Claudius Nero.
Arriving in Narni, Livius attempted to block the advance of the Carthaginian army invading the Italian peninsula.
Livius' wife, Calavia, was the daughter of Pacuvius Calavius, the chief magistrate of Capua in 217 BC.
