Romanos III Argyros, Byzantine emperor (b. 968)
Romanos III Argyros (Greek: Ρωμανός Γ΄ Αργυρός; Latinized as Romanus III Argyrus; 968 – 11 April 1034), or Argyropoulos was Byzantine Emperor from 1028 until his death. 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.

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.
