In Greek mythology, Cronus, Cronos, or Kronos, was the leader and youngest of the first generation of Titans, the divine descendants of Uranus, the sky, and Gaia, the earth. He overthrew his father and ruled during the mythological Golden Age, until he was overthrown by his own son Zeus and imprisoned in Tartarus. According to Plato, the deities Phorcys, Cronus, and Rhea were the eldest children of Oceanus and Tethys.

While the Greeks considered Cronus a cruel and tempestuous force of chaos and disorder, believing the Olympian gods had brought an era of peace and order by seizing power from the crude and malicious Titans, the Romans took a more positive and innocuous view of the deity, by conflating their indigenous deity Saturn with Cronus. Consequently, while the Greeks considered Cronus merely an intermediary stage between Uranus and Zeus, he was a larger aspect of Roman religion. The Saturnalia was a festival dedicated in his honour, and at least one temple to Saturn already existed in the archaic Roman Kingdom.
