Spurius Postumius Albinus Magnus was a general of ancient Rome, of patrician rank, of the 2nd century BC,[1] who was brother of Spurius Postumius Albinus, and probably son of Spurius Postumius Albinus Magnus.

He was left by his bro­ther as propraetor in command of the army in Africa in 110 BC. He marched to besiege Suthal, where the treasures of Jugurtha were held; but Jugurtha, under the promise of giving him a large sum of money, induced him to lead his army into a retired place, where he was suddenly attacked by the Numidian king, and only saved his troops from total destruction by allowing them to pass under the yoke (a symbolic gesture of submission to the enemy), and under­taking to leave Numidia in ten days.[2]
