Constantine, surnamed Lardys, (Greek: Κωνσταντίνος ὁ Λαρδῦς, romanized: Kōnstantinos ho Lardys) was one of the senior-most officials of the late reign of the Byzantine emperor Maurice (r. 582–602). Constantine Lardys was one of the leading members of the Byzantine Senate and a patrikios. He held the powerful post of praetorian prefect of the East some time during the latter part of Maurice's reign, although by 602 he held the post of curator of the palace of Hormisdas (curator domus divinae) and the extensive imperial estates attached to it. Constantine's tenure as praetorian prefect was unpopular due to the stringent financial policies pursued by Maurice.
