拉达（梵文：राधा）在印度史诗中是黑天的伴侣，亦是性力的其中一个象征。在摩诃婆罗多中，主要讲述黑天如何说服阿周那作战，对黑天自身的描述不多，只是轻描淡写地描述拉达。不过在诃利世系中，就有详尽描写黑天的身世，指拉达与黑天是青梅竹马的情侣，亦有讲述两人的爱情故事。最令人熟识拉达的则数中世纪诗人胜天的牧童之歌，在牧童之歌中，仔细描绘了黑天与拉达的性爱场面，致使拉达成为了印度性力学说的其中一个象征。

Radha (IAST: Rādhā, Hindi: राधा ), also called Radhika, Radharani, and Radhe, is a Hindu goddess who is almost always depicted alongside Krishna and features prominently within the theology of today's Vallabha and Gaudiya Vaishnava sects, which regards Radha as the original Goddess or Shakti. Radha is also the principal god of worship in the Nimbarka Sampradaya, as Nimbarka, the founder of the tradition, declared that Radha and Krishna together constitute the absolute truth. Radha is the most important gopi in Raas (Special kind of dance) with Lord Krishna. Radha is often referred to as Rādhārānī or "Radhika" in speech, prefixed with the respectful term 'Srimati' by devout followers. Gaudiya Vaishnavas, believe that in fact Radha is the original source from whom Goddess Lakshmi emanated.
