Taspar Qaghan or Tatpar Qaghan (Old Turkic: , Tatpar qaγan, 佗缽可汗/佗钵可汗, Pinyin: tuóbō kěhàn, Wade-Giles: t'o-po k'o-han) was the third son of Bumin Qaghan and Wei Changle (長樂公主), and the fourth khagan of the Turkic Khaganate (572–581). Unlike his father and older brothers he embraced Chinese culture, especially Buddhism. He was converted to Buddhism by the Qi monk Huilin, for whom he built a pagoda. Taspar's death marked the beginning of a long decline and subjugation of the Göktürks to China.
