Davaka was kingdom of
ancient India, located in current central region of
Assam state. The only reference to it comes from the 4th century Allahabad pillar inscription of Samudragupta, where it is mentioned as one of five frontier kingdoms of the
Gupta Empire. N K Bhattasali has identified it with
Dabaka in modern
Nagaon district, with the kingdom associated with the Kapili-Kallang river valley.
