(Ἐτυμοκλῆς) was one of the three Spartan envoys who, happening to be at Athens at the time of the incursion of Sphodrias into Attica (B. C. 378), were arrested by the Athenians on suspicion of having been privy to the attempt Their assurances, however, to the contrary were believed, and they were allowed to depart. Etymocles is mentioned by Xenophon and Plutarch as a friend of Agesilaus, and we hear of him again as one of the ambassadors sent to negotiate an alliance with Athens in B. C. 369. (Xen. Hell. 5.4. §§ 22, 23, 32, 6.5.33; Plut. Ages. 25.)
