Megaera is the name of one of the three Furies of Greco-Roman mythology. Her name means "jealous one". She punishes crimes relating to the breaking of oaths and infidelity, particularly marital infidelity. Her parentage is disputed; her parents may be Nyx and Erebus, or she may be born from the blood of Ouranos when he was castrated by Cronus.
