The name is taken from that of a hill in the Southern Indian town of Tirumala in which there is a Hindu temple dedicated to the Hindu God, Venkataswara (Lord of Venkata). Venkata itself is of uncertain meaning but according to the Brahmanda and Bhavishyottara Puranas it means “destroyer of sins.” The god Venkataswara is one of the many incarnations of Lord Vishnu in Hinduism.
Venkata was also borne by several South Indian kings.
Another form is Venkat.
