图塔蒂斯（英语：Toutatis）古罗马凯尔特神话神祇之一。盛行于高卢、不列颠等地区。其事迹反映于相关铭文等文物中，具有重要地影响与积极意义。

Toutatis or Teutates was a Celtic god worshipped in ancient Gaul and Britain. On the basis of his name's etymology, he has been widely interpreted to be a tribal protector. Today, he is best known under the name Toutatis (pronounced [towˈtaːtis] in Gaulish) through the Gaulish oath/catchphrase "By Toutatis!", invented for the Asterix comics by Goscinny and Uderzo. The spelling Toutatis, however, is authentic and attested by about ten ancient inscriptions. Under the spelling Teutates, the god is also known from a passage in Lucan.
