The Tungri (or Tongri, or Tungrians) were a tribe, or group of tribes, who lived in the Belgic part of Gaul, during the times of the Roman Empire. Within the Roman Empire, their territory was called the Civitas Tungrorum. They were described by Tacitus as being the same people who were first called "Germani" (Germanic), meaning that all other tribes who were later referred to this way, including those in Germania east of the river Rhine, were named after them. More specifically, Tacitus was thereby equating the Tungri with the "Germani Cisrhenani" described generations earlier by Julius Caesar
