(Κλεαρίδας), a friend of Brasidas, and apparently one of those young men whose appointment to foreign governments Thucydides considers to have been inconsistent with Spartan principles (4.132). He was made governor of Amphipolis by Brasidas; and in the battle there, in which Brasidas and Cleon were killed, he commanded the main body of the forces, B. C. 422. Clearidas afterwards distinguished himself in the quarrels which arose after the peace of Nicias, by giving up Amphipolis, not (as the terms required) to the Athenians, but to the Amphipolitans themselves. (Thuc. 5.10, 21, 34.)
