Brahmin (; Sanskrit: ब्राह्मण, romanized: brāhmaṇa) is a varna as well as a caste within the Hindu society. In Vedic- and post-Vedic Indian subcontinent, Brahmins were designated as the priestly class as they served as priests (purohit, pandit, or pujari) and spiritual teachers (guru or acharya). The other three varnas are the Kshatriya, Vaishya, and Shudra.

The traditional occupation of Brahmins is that of priesthood at Hindu temples or at socio-religious ceremonies, and rite of passage rituals such as solemnising a wedding with hymns and prayers. Traditionally, Brahmins are accorded the highest ritual status of the four social classes. Their livelihood is prescribed to be one of strict austerity and voluntary poverty ("a Brahmin should acquire what just suffices for the time, what he earns he should spend all that the same day"). In practice, Indian texts suggest that some Brahmins historically also became agriculturalists, warriors, traders, and had also held other occupations in the Indian subcontinent.
