(Εὐκράτης), the demagogue, according to the Scholiast, alluded to by Aristophanes (Aristoph. Kn. 130), where he speaks of a flax-seller who ruled next but one before Cleon. (Comp. Equit. 254.) He might possibly be the same as the father of Diodotus (Thuc. 3.41), who spoke against Cleon in the Mytilenaean debate, B. C. 427, but it is not very probable. The Eucrates mentioned in the Lysistrata (103) of Aristophanes as a general in Thrace is a different person, and probably the the same as the brother of Nicias spoken of below.
