In Greek mythology, Timandra (Τιμάνδρα) was one of the daughters of Leda and Tyndareus. Timandra married Echemus, the king of Arcadia, and with him had a son named Ladocus. Like her half-sister Helen and sister Clytemnestra, she was also unfaithful and deserted Echemus for Phyleus, the king of Dulichium.
