(Κλεομήδης), an Athenian, son of Lycomedes, was one of the commanders of the expedition against Melos in B. C. 416. He is mentioned also by Xenophon as one of the 30 tyrants appointed in B. C. 404. (Thuc. 5.84, &c.; Xen. Hell. 2.3.2.) Schneider's conjecture with respect to him (ad Xen. l.c.) is inadmissible.
