Romanus III (November 15, 1028 - April 11, 1034) was a Byzantine emperor. His family name Argyros, means "silver", and in Greek the emperor's name was Ρωμανός Αργυρός.

Romanus was an undistinguished Byzantine patrician, who was compelled by the dying emperor Constantine VIII to marry his daughter Zoë and become his successor. He showed great eagerness to make his mark as a ruler, but was mostly unfortunate in his enterprises. He spent large sums upon new buildings and in endowing the monks, and in his endeavour to relieve the pressure of taxation disorganized the finances of the state.

In 1030 he resolved to retaliate upon the incursions of the Muslims on the eastern frontier by leading a large army in person against Aleppo, but by allowing himself to be surprised on the march sustained a serious defeat at Azaz near Antioch. Though this disaster was retrieved by the successful defence of Edessa by George Maniaces and by the defeat of a Saracen fleet in the Adriatic, Romanus never recovered his popularity. His early death was supposed to have been due to poison administered by his wife.
