Aulus Sempronius Atratinus was a Roman Republican politician during the beginning of the 5th century BC.
During his first consular appointment in 497 BC, he consecrated the newly built Temple of Saturn in the Roman Forum.
[1] There had been a famine in Rome in the previous year and, in 491 BC during Sempronius' second consulship, a significant quantity of corn was imported from Sicily, and the question of how it should be distributed amongst the Roman citizens, together with tensions arising from the recent secession of the plebs, led to the exile and defection of Gnaeus Marcius Coriolanus after he unsuccessfully advocated the reversal of the reforms which arose from the secession, including the creation of the office of the tribunes.
The same historian writes that Sempronius Atratinus was involved in the wars against the Hernici and the Volsci in 487 BC.
Sempronius is included in a broken notice by Festus where he is listed among those who were burned at the Circus Maximus in 486 BC, possibly for conspiring with the consul Spurius Cassius Vecellinus.
