Aristaenos of Megalopolis was a powerful general of the Achaean League in Ancient Greece who served three terms beginning in 199 - 198 BC, 195 BC - 194 BC and 186 BC - 185 BC. Some historians think that he is to be identified with Aristaenos of Dyme, son of Timocades or Damocades, who was hipparch 208/07 BC. Others hold that they were two different persons.
