Marcus Atilius Regulus was a Roman consul in 294 BC. During his year, according to Livy's main source, he served against the Samnites and Apulians without great success until he vowed a temple to Jupiter Stator.^[1] After a victory at Interamna, Livy reports that a triumph was refused; the Acta Triumphorum however report that Regulus triumphed over the Volsones and the Samnites.^[2]

This Regulus is possibly related to the later homonymous consul of 267 BC.^{[citation needed]} He was probably the son of the consul of the same name in 335 BC.^[3]
