In Greek mythology, Taenarus ( or ; ) was the eponym of Cape Taenarum, Mount Taenarum, and the city Taenarus at Peloponnese. In different accounts, he is given as:

Taenarus, son of Zeus and brother of Calabrus and Geraestus. The three brothers were said to have sailed to Peloponnese and to have seized a portion of land there, where Taenarus founded a sanctuary of Poseidon known as "Taenarum".Stephanus of Byzantium, s.v. Tainaros Taenarus, son of Poseidon.Scholia ad Apollonius Rhodius, 1.179 Taenarus, son of Elatus, himself son of Icarius, and Erymede, daughter of Damasiclus; was said to have had the city, the mountain, and the harbor named after him.Scholia ad Apollonius Rhodius, 1.102 Stephanus (who writes of him as a son rather than a grandson of Icarius) considers him to be a figure distinct from Taenarus, son of Zeus.
