Atuatuca (or Aduatuca) is the name of two ancient fortified settlements located in the eastern part of modern Belgium, between the Scheldt and Rhine rivers. The oldest one, Atuatuca Eboronum, attested during the Gallic Wars (58–50 BC), was the stronghold of the Eburones. The other one, Atuatuca Tungrorum (modern Tongeren), founded around 10 BC, was the Roman-era capital of the Civitas Tungrorum, inhabited by the Tungri.
