Ino (Īˈnō) [key], in Greek mythology, daughter of Cadmus. She was the wife of Athamas, to whom she bore Learchus and Melicertes. She plotted to kill her stepchildren, Phrixus and Helle, but their mother, Nephele, saved them with the help of a winged ram (see Golden Fleece). Later, when Athamas went mad and killed Learchus, Ino and Melicertes leaped into the sea to their deaths and were changed into sea deities, Leucothea and Palaemon.
