"Shiva" is a major Hindu deity, and the Destroyer or transformer of the Trimurti, the Hindu Trinity of the primary aspects of the divine. In the Shaiva tradition of Hinduism, Shiva is seen as the Supreme God. In the Smarta tradition, he is regarded as one of the five primary forms of God.

Followers of Hinduism who focus their worship upon Shiva are called Shaivites or Shaivas. Shaivism, along with Vaiṣṇava traditions that focus on Vishnu and Śākta traditions that focus on the goddess Shakti are three of the most influential denominations in Hinduism.

Shiva is usually worshipped in the abstract form of Shiva linga. In images, he is generally represented as immersed in deep meditation or dancing the Tandava upon Apasmara Purusha, the demon of ignorance in his manifestation of Nataraja, the lord of the dance.
