For the Canadian mountain see Mount Syphax

Syphax was a king of the Masaesyles in western Numidia. Originally he was allied with the Romans against Carthage but his wife Sophonisbe convinced him to do just the opposite. In the Battle of the Great Plains of the Second Punic War, Syphax was defeated and captured by the Roman commander Gaius Laelius. Scipio Africanus, a Roman general, took him as a prisoner and he died in Rome in around 203 or 202 BC.
