再生族（梵文：Dvija），是指印度教头三个种姓的男性成员，即婆罗门、刹帝利、吠舍。

他们不只是肉体上出生，还要再由婆罗门主持一次入法礼（通常在8到12岁期间），经历一次精神上的出生，才算是真正的印度教徒（用一条圣线以区别自己与首陀罗）。之后就可参加宗教活动与学习吠陀（在传统的印度教社会入法礼象征重生和赋予参加仪式的权利，根据印度教的律法，一个人不参加入法礼与动物没有什么不同。）

与此相反的是首陀罗与贱民（一生族），他们没资格参与宗教活动（意指不受梵天的庇佑，而非指不受印度教社会的拘束）。

Dvija (Sanskrit: द्विज) means "twice-born". The concept is premised on the belief that a person is first born physically and at a later date is born for a second time spiritually, usually when he undergoes the rite of passage that initiates him into a school for Vedic studies. The term also refers to members of the three varnas in the traditional Hindu social system, or social classes — the Brahmins (priests and teachers), Kshatriyas (warriors), and Vaishyas (merchants) — whose Sanskara of Upanayana initiation was regarded as a second or spiritual birth.
