The Tencteri or Tenchteri or Tenctheri (in Plutarch's Greek, Tenterite and possibly the same as the Tenkeroi mentioned by Claudius Ptolemy if these were not the Tungri) were an ancient tribe, who moved into the area on the right bank (the northern or eastern bank) of the lower Rhine in the 1st century BC. They are known first from the surviving works of ancient authors such as Julius Caesar and Tacitus. In December 2015, archaeologists found remains of the Tencteri in The Netherlands.
