In Hindu culture, the term gotra (Sanskrit: गोत्र) is considered to be equivalent to lineage. It broadly refers to people who are descendants in an unbroken male line from a common male ancestor or patriline. Generally, the gotra forms an exogamous unit, with marriage within the same gotra being regarded as incest and prohibited by custom. The name of the gotra can be used as a surname, but it is different from a surname and is strictly maintained because of its importance in marriages among Hindus, especially among castes.

Pāṇini defines gotra as apatyam pautraprabhrti gotram (IV. 1. 162), which means "the word gotra denotes the descendance (or descendants), apatya, of a couple consisting of a pautra, a son and a bharti, a mother, i.e. a daughter-in-law."

==Foundational structure== According to the Brihadaranyaka Upanishad 2.2.4, Kashyapa, Atri, Vasistha, Vishvamitra, Gautama Maharishi, Jamadagni and Bharadvaja are seven sages (also known as saptarishi) and Jambu Maharishi is another sage (also known as Renuka, who belongs to Kashyapa). The progeny of these eight sages are declared to be gotras. This enumeration of seven primary and one secondary gotra seems to have been known to Pāṇini. The offspring (apatya) of these seven are gotras and others than these are called gotrāvayava.
