In Greek mythology, Lamedon was the younger son of Coronus the Sicyonian, and brother to Corex. After his older brother died without issue, Lamedon was to succeed him, but the kingdom was seized by Epopeus. However, Epopeus died of a wound he had received in the battle against Nycteus, and Lamedon took over as his heir; according to Pausanias, Lamedon was responsible for giving Antiope up to Lycus.
