Aulus Postumius Albinus
- For other persons with the cognomen "Albus" or "Albinus", see Albinus (cognomen).
Aulus Postumius Albinus was a politician of the Roman Republic, and second consul in 99 BC with M. Antonius. Aulus Gellius quotes the words of a senatus consultum passed in their consulship in consequence of the spears of Mars having moved. Cicero mentions him as being a good orator.
He was the grandson of Spurius Postumius Albinus Magnus, and probably son of Aulus Postumius Albinus. He was also the adoptive father of Decimus Junius Brutus Albinus, one of Julius Caesar's assassins (from whom Decimus Brutus adopted the name of Albinus).
