Aulus Sempronius Atratinus was a member of the patrician branch of the Sempronia gens he served as the consular tribune of the Roman Republic in 444 BC.^[1]

Aulus was elected consular tribune alongside Lucius Atilius and Titus Cloelius Siculus in 444 BC. According to the Roman historian Titus Livius, there were "some who, ... say that three military tribunes were elected on account of the Veientian War being added to the war of the Aequans and the Volscians and to the revolt of the Ardeates, because two consuls could not execute so many wars together, these tribunes [were] invested also with the authority and insignia of consuls". On the third month however of being elected, they resigned in pursuance of a decree of the augurs, as if unduly elected; because Gaius Curtius, who had presided at the election, had not selected his tent with due regard to ceremony.^[2]
