Tubdzhak, or Tuptzhaka, was a kan of Bulgaria who ruled between 587 and 602. Various sources report that he ruled for about fifteen years. He was the father of Bat Orkan, who ruled from 602 to 603, and of Gostun, or Alburi, who ruled from 603 to 605 before being killed in 618.

The name or epithet Tubdzhak is associated with the Avar ethnic group. Tubdzhak was the son of Kan Tutra and the father of Kan Organa.

According to the historical chronicle Гази-Барадж тарихи (Gazi-Baradj Tarihi), completed before 1246, Tubdzhak died in 605 after a fifteen-year reign. He left his elder son Bat Orkan a vast principality stretching from the Carpathians to Aksu. According to the same source, Tubdzhak ruled from 590 to 605.
