In Greek mythology, Autesion (Ancient Greek Αὐτεσίων) is a king of Thebes, son of Tisamenus and descendant of Polynices. At an oracle's command he leaves Thebes for the Peloponnese among the Dorians; through his daughter Argeia he is grandfather of the Spartan twin kings Eurysthenes and Procles.

I.From Thebes to the Dorians
Apollodorus, Pausanias, Herodotus, and Strabo know Autesion as son of Tisamenus, grandson of Thersander, and great-grandson of Polynices and Argia. He succeeds at Thebes, then — by oracle — migrates to join the Dorians in the Peloponnese. Pausanias says the Erinyes of Laius and Oedipus at last vented their wrath on him.
His children include Theras and Argeia; by Argeia, Aristodemus fathers Eurysthenes and Procles, the twin founders of the dual Spartan kingship. Nonnus also uses the name for a warrior slain in the Dionysiaca — a separate figure.
II.Homonym care
The atlas id autesion-theban is the Theban–Dorian king alone, not Nonnus' Indian-war casualty.
