The Vāyu Purāṇa (वायु पुराण) is one of the 18 Mahāpurāṇas in Hindu literature. It is named after the wind god Vāyu, who plays a role as narrator and intermediary. This Purāṇa is considered among the oldest, with many scholars dating its core to before the Gupta period (3rd–4th century CE).
It shares significant similarities with the Brāhmaṇḍa Purāṇa, and some chapters are nearly identical between the two.
