Marcus Atilius M.f. M.n. Regulus (fl. 213 BC), a son of Marcus Atilius Regulus, the consul captured during the First Punic War, and grandson of Marcus Atilius Regulus (consul 294 BC), was Roman consul for the year 227 BC, together with Publius Valerius Flaccus, and consul suffectus for 217 BC replacing Gaius Flaminius who was killed in battle at Lake Trasimene. Atilius Regulus agreed to accompany Gaius Terentius Varro and Lucius Aemilius Paullus (consul 219 BC) along with the other former consul Gnaeus Servilius Geminus, but returned to Rome pleading ill-health and old age. He thus survived the massacre of the Roman army at the Battle of Cannae.

Atilius Regulus was chosen a censor in 214 BC along with Publius Furius Sp.f. Philus, but had to resign his office when his colleague was killed in battle in 213 BC.

His younger brother Gaius was killed in the Battle of Telamon in 225 BC, the year of his consulship. An uncle Gaius was also twice consul during the First Punic War.
