Aulus Sempronius Atratinus (consular tribune 444 BC)

Aulus Sempronius Atratinus (fl. 5th century BC) was a statesman of the first century of the Roman Republic.

In 444 BC, he was elected to the first collegium of military tribunes with consular power with two other colleagues, Titus Cloelius Siculus and Lucius Atilius Luscus. This was the first time that military tribunes exercised power in Roman Republic, and this election was quickly challenged. The three abdicated after three months in office.
