Kamadhenu (Sanskrit: कामधेनु, [kaːmɐˈdʱeːnʊ], Kāmadhenu), also known as Surabhi (सुरभि, Surabhi or सुरभी, Surabhī), is a divine bovine-goddess described in Hinduism as the mother of all cows. She is a miraculous cow of plenty who provides her owner whatever they desire and is often portrayed as the mother of other cattle. In iconography, she is generally depicted as a white cow with a female head and breasts, the wings of a bird, and the tail of a peafowl or as a white cow containing various deities within her body. Kamadhenu is not worshipped independently as a goddess. Rather, she is honored by the Hindu veneration of cows, who are regarded as her earthly embodiments.

Hindu scriptures provide diverse accounts of the birth of Kamadhenu. While some narrate that she emerged from the churning of the cosmic ocean, others describe her as the daughter of the creator god Daksha, and as the wife of the sage Kashyapa. Still other scriptures narrate that Kamadhenu was in the possession of either Jamadagni or Vashista (both ancient sages), and that kings who tried to steal her from the sage ultimately faced dire consequences for their actions. Kamadhenu plays the important role of providing milk and milk products to be used in her sage-master's oblations; she is also capable of producing fierce warriors to protect him. In addition to dwelling in the sage's hermitage, she is also described as dwelling in Goloka—the realm of the cows—and Patala, the netherworld.
