Oenomaiis was the name of two noted characters. The first was a king of Pisa who killed all the suitors of his daughter, Hippodamia, until he was himself killed by Pelops.

He was said to own an extensive fertile district of land where presumably there were vines, since his name seems to mean 'greedy with wine', from oinos, 'wine' and margos, 'raging mad', 'greedy', 'lustful'. The other character was a Trojan killed by Idomeneus. We have no evidence that he was 'lustful with wine' but that is what his name means.
