Romanos III Argyros (Greek: Ῥωμανός Ἀργυρός, romanized: Rōmanos Argyros; Latinized Romanus III Argyrus; 968 – 11 April 1034), or Argyropoulos, was Byzantine Emperor from 1028 until his death in 1034. He was a Byzantine noble and senior official in Constantinople when the dying Constantine VIII forced him to divorce his wife and marry the emperor's daughter, Zoë. Upon Constantine's death three days later, Romanos took the throne.
He was recognized as emperor by jure uxoris (by right of his wife), and Zoe became empress. Romanos has been recorded as a well-meaning but ineffective emperor. He disorganised the tax system and undermined the military, personally leading a disastrous military expedition against Aleppo. He fell out with his wife and foiled several attempts on his throne, including two which revolved around his sister-in-law Theodora. He spent large amounts on the construction and repair of churches and monasteries. He died after six years on the throne, allegedly murdered, and was succeeded by his wife's young lover, Michael IV.
