Tantalus is an extinct cinder cone in the southern Koʻolau Range on the Hawaiian Island of Oʻahu. It also has a summit crater, Tantalus Crater. The cinder cone formed after the demise of Koʻolau Volcano, during a time of rejuvenated stage volcanism in southeastern Oʻahu that also formed Punchbowl Crater, Diamond Head and Koko Head. Tantalus overlooks the modern city of Honolulu, which is built on top of Tantalus cinders.

The southern slope of Tantalus was bombed in Operation K, Japan's unsuccessful second attack on O'ahu, which took place March 4, 1942.

Today, Tantalus is a popular hiking destination.
