Vritra (, , ) is a danava in Hinduism. He serves as the personification of drought, and is an adversary of the king of the devas, Indra. As a danava, he belongs to the race of the asuras. Vritra is also known in the Vedas as Ahi ( ). He appears as a human-like serpent blocking the course of the Rigvedic rivers, and is slain by Indra with his newly forged vajra.
