Aulus Atilius Calatinus (d. by 216 BC) was a politician and general in Ancient Rome. He was the first Roman dictator to lead an army outside Italy (then understood as the Italian mainland), when he led his army into Sicily. He was consul in 258 BC and again in 254 BC, a praetor and triumphator in 257 BC, and finally a censor in 247 BC. Calatinus must have died by 216 BC, because Marcus Fabius Buteo (censor in 241 BC) was named the oldest living ex-censor; Calatinus would have been senior to him in terms of the date of censorship and their respective ages.
