Tisamenus (Ancient Greek: Τισαμενός) was a king of Thebes, son of the Epigon Thersander and Demonassa daughter of Amphiaraus. Still a minor when Telephus killed his father in Mysia, he was under the regency of Peneleos until he came of age; he later succeeded to the Cadmean throne and was followed by his son Autesion. The atlas keeps him distinct from Tisamenus son of Orestes, the last Pelopid king of Argos and Sparta.

I.Parentage and minority
Tisamenus was son of Thersander, the Epigon who recovered Thebes, and Demonassa, daughter of the seer Amphiaraus. When Thersander fell in Mysia on the Greeks' first attempt against Troy, Tisamenus was still too young to lead; Pausanias records that Peneleos commanded the Boeotian host in his stead and acted as regent.
Not to be confused with tisamenus, son of Orestes and Hermione (or Erigone), the last Pelopid king driven out by the Heracleidae.
II.Kingship and succession
After Peneleos was killed at Troy by Eurypylus son of Telephus, Tisamenus was chosen king of Thebes. Little is told of his reign itself. Pausanias notes that the Erinyes of Laius and Oedipus did not pursue him, but did pursue his son Autesion, who migrated to the Dorians at the oracle's bidding; through Autesion the line reaches Theras, eponym of Thera.
