Cleondas of Thebes was an ancient Greek athlete listed by Eusebius of Caesarea as a victor in the stadion race of the 41st Olympiad (616 BC).^[1] Dionysius of Halicarnassus refers his name as "Kleonidas".^[2] He appears to be the only Theban runner to win at the Olympic Games, while there were at least two more Boeotians in the same category: Oxythemis of Coroneia in 732 BC and Micion of Boeotia in 196 BC.
