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.
[1] He presumably returned to Italy after relations between the Emperor and Bonifacius were restored in 429 or 430.
From either the same year or from 440 until 448, he was magister utriusque militiae (though despite the title he remained under the command of Aetius), and organized defences against the Vandals.
[1] The name Sigisvultus is of German origin, and is also written Sigisvult, Segisvultus, or Sigisvuldus.
