In Greek mythology, Olenus (; Ancient Greek: Ὤλενος Olenos) was the name of several individuals:
- Olenus, son of Hephaestus and father of Helike and Aex, two nurses of infant Zeus. A city in Aulis was named for him.[1]
- Olenus, son of Zeus and Anaxithea[2] (or Hippodamia[3]), daughter of Danaus. He was the eponymous ruler of the city Olenus in Achaea. Olenus was succeeded by Crinacus (Crineus), another bastard son of Zeus.[4]
- Olenus, father of Tectaphus, a Lapith.[5]
- Olenus, a man who lived on Mount Ida. His wife Lethaea claimed she was more beautiful than any goddess. They were both turned to stone; although Olenus could have avoided this fate, he chose to be with his wife.[6]
- Olenus, a Lelegian, father of Phoceus. His son was killed by the Argonauts.[7]
