Constantine III (born May 3, 612—died April or May, 641) was a Byzantine emperor from January to April or May 641. He was coemperor with his father, Heraclius, from 613 and with his brother Heraclonas from 638. During his reign, court intrigues nearly led to civil war, which was prevented by his death. It was rumoured that he was poisoned by order of his stepmother, but he may have died of tuberculosis.
