Spurius Postumius Albinus was a politician of Ancient Rome, of patrician rank, of the 4th century BC. He was consul in 334 BC, and invaded, with his colleague Titus Veturius Calvinus, the country of the Sidicini. But on account of the great forces which the enemy had collected, and the report that the Samnites were coming to their assistance, a dictator was appointed, Publius Cornelius Rufinus.
