Gautam Brahmins are those Hindu Brahmins, who affiliate either with Gautam gotra and/or with Gautam Dharmasūtra.
The name Gautam (Sanskrit: गौतम, a vrddhi patronymic of Gotama and also transliterated as Gautama or Gauthama) is one of the ancient Indian names and is derived from the Sanskrit roots "gŐ(गः)" and "tama (तम)". "Tama" means “darkness” and "gŐ" means inter alia "bright light". Together, they indicate that one, who dispels darkness (i.e., ignorance) by his brilliance (i.e., spiritual knowledge).
