The Cugerni (or Cuberni or Guberni) was Germanic tribal grouping with a particular territory within the Roman province of Germania Inferior, which later became Germania Secunda. More precisely they lived near modern Xanten, and the old Castra Vetera, on the Rhine. This part of Germania Secunda was called the Civitas or Colonia Traiana (polity or colony of Trajan), and it was also inhabited by the Betasii. The region of the Cugerni was in the centre of action during the Batavian revolt, with different tribal groups taking different sides. The Cugerni took the side of Gaius Julius Civilis.
