Kikata was an ancient kingdom in what is now India, mentioned in the Vedas. It is believed that they were the forefathers of Magadhas. It lay to the south of Magadha Kingdom.
A section in the Rigveda (RV 3.53.14) refers to the Kīkaṭas, a tribe which most scholars have placed in Bihar (Magadha).
Zimmer has argued, in referring to Yaksa, that they were a non-Aryan people. According to Weber, they were a Vedic people, but were sometimes in conflict with other Vedic people.
