In Greek mythology, the Titans (Greek: Τιτάν - Ti-tan; plural: Τιτᾶνες - Ti-tânes) were a race of powerful deities, descendants of Gaia and Uranus, that ruled during the legendary Golden Age.

In the first generation of twelve Titans, the males were Oceanus, Hyperion, Coeus, Cronus, Crius and Iapetus and the females were Mnemosyne, Tethys, Theia, Phoebe, Rhea and Themis. The second generation of Titans consisted of Hyperion's children Eos, Helios, and Selene; Coeus's daughters Leto and Asteria; Iapetus's sons Atlas, Prometheus, Epimetheus, and Menoetius; Oceanus' daughter Metis; and Crius's sons Astraeus, Pallas, and Perses.

The Titans were overthrown by a race of younger gods, the Olympians, in the Titanomachy ("War of the Titans"). This represented a mythological paradigm shift that the Greeks may have borrowed from the Ancient Near East.

Greeks of the classical age knew of several poems about the war between the Olympians and Titans. The dominant one, and the only one that has survived, was in the Theogony attributed to Hesiod. A lost epic, Titanomachia—attributed to the legendary blind Thracian bard Thamyris—was mentioned in passing in an essay On Music that was once attributed to Plutarch. The Titans also played a prominent role in the poems attributed to Orpheus. Although only scraps of the Orphic narratives survive, they show interesting differences with the Hesiodic tradition.

Titan most often refers to:

The term "mythology" can refer either to the study of myths (e.g., comparative mythology), or to a body or collection of myths (a mythos, e.g., Inca mythology). In folkloristics, a myth is a sacred narrative usually explaining how the world or humankind came to be in its present form, although, in a very broad sense, the word can refer to any traditional story. Myths typically involve supernatural characters and are endorsed by rulers or priests. They may arise as overelaborated accounts of historical events, as allegory for or personification of natural phenomena, or as an explanation of ritual. They are transmitted to convey religious or idealized experience, to establish behavioral models, and to teach.

Early rival classifications of Greek mythos by Euhemerus, Plato's Phaedrus, and Sallustius were developed by the neoplatonists and revived by Renaissance mythographers as in the Theologia mythologica (1532). Nineteenth-century comparative mythology reinterpreted myth as evolution toward science (E. B. Tylor), "disease of language" (Max Müller), or misinterpretation of magical ritual (James Frazer). Later interpretations rejected opposition between myth and science, such as Jungian archetypes, Joseph Campbell's "metaphor of spiritual potentiality", or Lévi-Strauss's fixed mental architecture. Tension between Campbell's comparative search for monomyth or Ur-myth and anthropological mythologists' skepticism of universal origin has marked the 20th century. Further, modern mythopoeia such as fantasy novels, manga, and urban legend, with many competing artificial mythoi acknowledged as fiction, supports the idea of myth as ongoing social practice.
