Avantivarman is believed to be the last king of the Varman dynasty of Kamarupa in present-day North-East India.

No direct evidence of this king exists, nor does this name appear anywhere in a historical record — the name Avanti Varma itself is reconstructed from the benedictory verses of a Sanskrit play Mudrarakshasa by Vishakhadatta.^[1] According to some scholars, the "Avantivarma" of Mudrarakshasa is actually another king of the Maukhari dynasty.^[2]

According to Bargaon grant of Ratnapal, Mlechchha king Salasthambha took over the rule of Kamarupa from the descendants of Naraka.^[3] K.L. Barua states that there was a Mlechha revolt in Kamarupa and the leader of the Mlecchas usurped the throne by deposing Bhaskaravarman's immediate successor Avantivarman.^[4] Mukunda Madhava Sharma theorizes that Salasthambha must have overthrown the immediate successor of Bhaskaravarman.^[5] P.C Choudhury opines that Salasthambha, the founder of Mlechchha dynasty was known as Avantivarman.^[6]
