Erymneus (; fl. c. 110 BC) was a Peripatetic philosopher in
Ancient Greece.
Erymneus succeeded Diodorus of Tyre as scholarch (leader) of the Lyceum. Very little is known about him, and he is known only because he is mentioned by Athenaeus.[Athenaeus, Deipnosophistae, v. 211e] He instructed Aristion, whose identity is obscure, in philosophy.[Canfora & Ryle, The Vanished Library (University of California Press, 1990), p. 52.] He led the school while Apellicon of Teos was a member. The school had a renewed vitality under Erymneus.[Lynch, J. P., Aristotle's School (University of California Press, 1972), p. 202.]
