The Nemetes or Nemeti were a tribe settled along the Upper Rhine by Ariovistus in the 1st century BC.
Their area of settlement was the contact zone between Celtic (Gaulish) and Germanic peoples. According to Tacitus, the Nemetes were "unquestionably Germanic". The name of the tribe, however, is Celtic as the name of its main town Noviomagus meaning novios 'new' and magos 'plain', 'market' (cf. Welsh maes 'field', Old Irish mag 'plain'), as are those of several gods worshipped in their territory, including Nemetona, who is thought to have been their eponymous deity. Both of these names are taken to be derivations from the Celtic stem nemeto- "sacred grove".
