The Brahmanas (; Sanskrit: ब्राह्मणम्, Brāhmaṇam) are Vedic śruti works attached to the Samhitas (hymns and mantras) of the Rig, Sama, Yajur, and Atharva Vedas

They are a secondary layer or classification of Sanskrit texts embedded within each Veda, often explain and instruct Brahmins on the performance of Vedic rituals (in which the related Samhitas are recited)

In addition to explaining the symbolism and meaning of the Samhitas, Brahmana literature also expounds scientific knowledge of the Vedic Period, including observational astronomy and, particularly in relation to altar construction, geometry

Divergent in nature, some Brahmanas also contain mystical and philosophical material that constitutes Aranyakas and Upanishads

Each Veda has one or more of its own Brahmanas, and each Brahmana is generally associated with a particular Shakha or Vedic school

Less than twenty Brahmanas are currently extant, as most have been lost or destroyed

Dating of the final codification of the Brahmanas and associated Vedic texts is controversial, as they were likely recorded after several centuries of oral transmission

The oldest Brahmana is dated to about 900 BCE, while the youngest are dated to around 700 BCE
