Mount Cynthus (Greek: Κύνθος, Kýnthos) is located on the isle of Delos, part of the Greek Cyclades.
In Greek mythology, Leto gave birth to Apollo and Artemis on this island, having been shunned by Zeus' wife Hera who was extremely jealous of his liaison with Leto. Artemis is thus also referred to as Cynthia.
In modern times, this island is a major archaeological site and a favoured tourist spot.
