Michael V Kalaphates () was Byzantine emperor for four months in 1041–1042. He was the nephew and successor of Michael IV and the adoptive son of Michael IV's wife Empress Zoe. He was popularly called "the Caulker" (Kalaphates) in accordance with his father's original occupation. Family Michael V was the son of a couple named Stephen and Maria. His birth date is not known, but is sometimes given as 1015, probably because he was considered "young" in 1035. Michael's mother was a sister of the Byzantine emperor Michael IV and Stephen had been a caulker before becoming an admiral under Michael IV and then botching an expedition to Sicily. Although the emperor preferred another of his nephews, the future Michael V was advanced as heir to the throne by his other uncle John the Orphanotrophos and the Empress Zoe.

On the night of 18 April to 19 April 1042, Michael V banished his adoptive mother and co-ruler Zoe, for plotting to poison him, to the island of Principo, thus becoming sole emperor. His announcement of the event in the morning led to a popular revolt; the palace was surrounded by a mob demanding Zoe's immediate restoration. The demand was met, and Zoe was brought back, though still in a nun's habit. Presenting Zoe to the crowds in the Hippodrome did not quell the public's outrage over Michael's actions. The masses attacked the palace from multiple directions. The emperor's soldiers attempted to fight them off and by April 21, an estimated three thousand people from both sides had died. Once inside the palace, the mob pillaged valuables and tore up the tax rolls. Also on 21 April 1042 Zoe's sister Theodora, who had been removed from her nunnery against
