In Greek mythology, Melanion (/məˈlæniən/; Ancient Greek: Μελανίων) or Meilanion (Μειλανίων) may refer to two distinct characters:
- Melanion, the Lacedaemonian son of the Pelopid Argeios and Hegesandra, daughter of King Amyclas of Sparta. He was the brother of Alector and Boethoos.[1][2]
- Melanion, also called Hippomenes, Arcadian son of Amphidamas and husband of Atalanta.[3]
