The Temple of Jupiter Invictus (Latin: Aedes Iovis Invicti, lit. 'Temple of Jupiter the Unconquered'), sometimes known as the Temple of Jupiter Victor (Latin: Aedes Iovis Victoris, lit. 'Temple of Jupiter the Conqueror'), was a temple on the Palatine Hill of ancient Rome.
The date of the temple's construction is uncertain, but it came to eclipse an earlier temple of Jupiter Victor on the Quirinal Hill, with which it is sometimes confused. It was credited as the sight of several divine portents during the imperial period, and may have been the shrine briefly dedicated to the Syrian god Elagabal by the emperor Elagabalus in the third century CE. Since the 1950s, the temple has been considered completely lost.
