- Aeetes — Mythological king of Colchis, son of the sun god Helios and the nymph Perseis, brother of the sorceress Circe and father of Medea.

- Aegeus — Mythical king of Athens, son of Pandion II and father of the hero Theseus, recognized in Hellenic legends for founding early Athenian power structures.

- Aegialeus — The name borne by several distinct figures in Greek mythology, the most prominent being the king of Argos, son of Adrastus, recognized as one of the Epigoni (the descendants of the Seven against Thebes).

Another mythological Aegialeus is the founding king of Sicyon, regarded as a son of the river god Inachus.
- Aegisthus — A tragic figure in Greek mythology, the adulterous son of Thyestes and his own daughter Pelopia, born as an instrument of bloody vengeance within the cursed house of the Pelopidae.

- Aegos — A shortened form or toponymic reference associated with Aegospotami (Goat's River), an ancient river and settlement in the Thracian Chersonese, famous as the site of the decisive naval battle in 405 BC where the Spartan fleet led by Lysander destroyed Athenian forces, ending the Peloponnesian War.

- Aesacus — A character in Greek and Roman mythology, son of King Priam of Troy and the nymph Alexirhoe, endowed with the prophetic gift of interpreting nocturnal dreams.

- Aeson — A character in Greek mythology, legendary king of Iolcus in Thessaly, son of Cretheus and Tyro, and father of the hero Jason.

- Aethalides — A character in Greek mythology, son of the god Hermes and Eupolemeia, the legendary herald of the Argonauts during the quest for the Golden Fleece. He was endowed by his father with an absolutely infallible and eternal structural memory, which did not fade even after death or after crossing the river Lethe, allowing his soul to remember all successive reincarnations undergone during its cosmic migration.
- Aethra — The Latinized name of Aethra, a character in Greek mythology, daughter of King Pittheus of Troezen and mother of the Athenian hero Theseus (born from her union with King Aegeus or the god Poseidon).

- Agamemnonides — A rare patronymic form used in classical literature and mythology to denote a direct descendant of King Agamemnon, applied especially to his son, Orestes. This structural epithet emphasizes the genealogical link and tragic heritage of the House of Atreus within Greek epics and tragedies.
