The Nemetes (; ), by modern authors sometimes called Nemeti, were an ancient Germanic tribe living by the Rhine where Ariovistus had led them, the Suebi and other allied Germanic peoples in the second quarter of the 1st century BC. The Roman name for Speyer, Noviomagus Nemetum, reflects this city's status as the Nemetes' tribal capital. According to Tacitus, they were "unquestionably Germanic". The name of the tribe, however, is Celtic as the name of its main town Noviomagus meaning noviios 'new' and magos 'plain', 'market' (cf. Old Irish mag 'plain'), as are those of a number of gods worshipped in their territory, including Nemetona, who is thought to have been their eponymous deity. Both of these names derive from the Celtic root nemeto-, referring to sacred spaces.
