Aeacus (; also spelled Eacus; Ancient Greek: Αἰακός) was a king of the island of Aegina in Greek mythology. He was a son of Zeus and the nymph Aegina, and the father of the heroes Peleus and Telamon. According to legend, he was famous for his justice, and after he died he became one of the three judges in the underworld alongside Minos and Rhadamanthus. In another story, he assisted Poseidon and Apollo in building the walls of Troy.

In Greek mythology, Queen Endeïs (; Ancient Greek: Ενδηίς or Ενδαΐς) was the wife of King Aeacus and mother of the heroes Telamon and Peleus (since Peleus was the father of Achilles and Telamon was the father of Ajax the Great and Teucer, Endeïs was the grandmother of Achilles, Ajax and Teucer). The name is a dialect variant of Engaios (Ἐγγαῖος, "in the earth").
