(Εὐρυδαμίδας), son of Agis IV., king of Sparta. At the death of his father he was yet a child. According to Pausanias, he was poisoned by Cleomenes with the assistance of the ephors, and the royal power of his family transferred to his brother Eucleides. The truth of this story is, however, questionable. (Paus. 2.9.1, 3.10.6; Manso, Sparta, vol. 3.2, p. 136.)
