Cape Miseno (Italian: Miseno, Latin: Misenum, Ancient Greek: Μισήνον) is the headland that marks the northwestern limit of the Gulf of Naples as well as the Bay of Pozzuoli in southern Italy. The cape is directly across from the island of Procida and is named for Misenus, a character in Virgil's Aeneid.
Historically, the cape was important to the Romans since it was a natural shelter for passage into the inner harbor of Portus Julius, the home port for the Roman western imperial fleet. Mythologically, important sections of the Aeneid play out in the Gulf of Naples: This is where Aeneas' comrade, Misenus, master of the sea-horn — the conch-shell — made "the waves ring" with his music and challenged the sea-god Triton to musical battle. He was dashed into the sea and killed by "jealous Triton". Then:
- "...Pious Aeneas
- sets up a mighty tomb above Misenus
- bearing his arms, a trumpet, and an oar;
- it stands beneath a lofty promontory,
- now known as Cape Misenus after him:
- it keeps a name that lasts through all the ages."
