Flavius Sigisvultus (fl. 427–448) was a general of the late Western Roman Empire. He was sent in 427 to command the war in Africa against a rebellious general, Bonifacius, after previous generals had been defeated by the latter, and may have been appointed comes Africae, succeeding Bonifacius. He seized Hippo and Carthage, and as an Arian himself, sent an Arian bishop, Maximinus, to dispute with Augustine of Hippo in 427 or 428. He presumably returned to Italy after relations between the Emperor and Bonifacius were restored in 429 or 430.
