In Greek mythology, Dymas was a Dorian hero. He was considered to be the eponymous hero of one of the three tribes of the Dorians, the Dymaneis; his brothers, Pamphylos and Hyllos, were associated with the remaining two. Originally, these three heroes were identified as the sons of Doros, after whom the Dorians are named, but by at least the sixth century BCE they were considered to be the sons of Aigimios, who was himself considered to be Doros's son.
