Constans (floruit 412–414) was a general of the Eastern Roman Empire.
Constans was magister militum per Thracias in 412. In 414 he held the consulship (possibly while he still was magister militum) in Constantinople. His name may be a clue of a potential relationship to Constantius III, his Western colleague in the consulate and later Western emperor, but the sources do not mention any relationship between the two.
