Tong Yabghu Qaghan (died 628) is khagan of the Western Turkic Khaganate from 618 to 628.

His name is usually translated as "Tiger Yabgu" in Old Turkic.

Another interpretation of his name is "sufficiency" or "completeness".

He is the brother of Sheguy (r. 611-618), the previous khagan of the western Göktürks, and is a member of the Ashina clan.

Tong Yabghu's reign is generally regarded as the zenith of the Western Göktürk Khaganate.
