Darius (Greek: ÃÂñÃÂõïÿÃÂ; floruit 425âÂÂ437) was a politician of the Eastern Roman Empire.
Darius was a Praetorian prefect of the East. He is attested in office between 28 August 436, when the law preserved in Codex Theodosianus XI 1.37<sup>a</sup> was addressed to him, to 16 March 437, the day in which another law, preserved in Codex Theodosianus VI 23.4<sup>a</sup>, was addressed to him.
He might have been in office until October 437; in that case, he was in Constantinople and received a copy of the not-yet published Codex Theodosianus.
Darius is to be identified with the Praetorian prefect "Damarius", whose wife Aeliana had a vision in 425, in Constantinople.
Darius may be the envoy who negotiated on behalf of Placidia with Bonifatius.
