In the Roman Republic, the Pontifex Maximus was the highest office in the state religion of ancient Rome and directed the College of Pontiffs (Collegium Pontificum). Residing in the Domus Publica ("State House") and officed in the Regia, he had both political and religious authority.

Known Pontifices Maximi
- The first Roman Emperor Augustus assumed the title of Pontifex Maximus after the death of Marcus Aemilius Lepidus (who was apart of the Second Triumvirate alongside Augustus and Marcus Antonius) in 13 BC; afterward, the chief priest's office was moved from the Regia to Augustus' palace, the Domus Augusti ("House of Augustus"), located on the Palantine Hill in Rome.
