For Aristomenes, regent of Ptolemaic Egypt, see Aristomenes of Alyzia.
Aristomenes(Greek: Ἀριστομένης) was a king of Messenia, celebrated for his struggle with the Spartans in the Messenian Wars, and his resistance to them on Mount Ira for 11 years. At length the mountain fell to the enemy, while he escaped and was snatched up by the gods; he died at Rhodes.
