Indra (Devanagari: इन्द्र) or Śakra is the King of the gods or Devas and Lord of Heaven or Svargaloka in Hindu mythology. He is also the God of War, Storms, and Rainfall.

Indra is one of the chief deities in the Rigveda. He is celebrated as a demiurge who pushes up the sky, releases dawn (Ushas) from the Vala cave, and slays Vṛtra; both latter actions are central to the Soma sacrifice. On the other hand, he also commits (like Zeus) many kinds of mischief (kilbiṣa) for which he is sometimes punished. He has many epithets, notably vṛṣan the bull, and vṛtrahan, slayer of Vṛtra and maghavan "the bountiful'. Indra appears as the name of an arch-demon in the Zoroastrian religion, while his epithet Verethragna appears as a god of victory.
