Flavius Astyrius[1] or Asturius[2] (441–449) was a general and a politician of the Western Roman Empire.
Astyrius was the father-in-law of Merobaudes and belonged to an aristocratic family.[3]
He followed a military career: between 441 and 443 he is attested as dux or magister utriusque militiae. In 441 he was in Tarraconensis (Spain), where he defeated the Bagaudae.[4] In 443 he was succeeded by his son-in-law Merobaudes.[5]
He was appointed consul for the year 449. At the beginning of his office he was in Gaul (probably in the capital city of the praetorian prefecture, Arelate), and Nicetius delivered a panegyric in his honour.[6]
A consular diptych produced by Astyrius in 449 is preserved at Liège. The diptych shows Astyrius seated on a curule chair wearing complete consular regalia and the inscription Flavius Astyrius vir clarissimus[7] et inlustris[8] comes[9] ex magistro utriusque militiae consul ordinarius.[10]
