Eleftherios Floros (died 431 BC) was a member of the Cult of Kosmos. In 431 BC, he and Sergios Condos were sent to guard Elpenor at Kirrha, and they attempted to kill the mercenary Kassandra when she threatened Elpenor over his insults against her family. However, Kassandra slew both of the men, who had bought Elpenor enough time to escape.
