Germanic law is a scholarly term used to describe a series of commonalities between the various law codes of the early Germanic peoples. These were compared with statements in Tacitus and Caesar as well as with high and late medieval law codes from Germany and Scandinavia. Until the 1950s, these commonalities were held to be the result of a distinct Germanic legal culture. Scholarship since then has questioned this premise and argued that many "Germanic" features instead derive from provincial Roman law. Although most scholars no longer hold that Germanic law was a distinct legal system, some still argue for the retention of the term and for the potential that some aspects of the Leges in particular derive from a Germanic culture. Scholarly consensus as of 2023 is that Germanic law is best understood in opposition to Roman law, in that it was not "learned" and incorporated regional pecularities.

The Germanic peoples were historical groups of people that once occupied Northwestern and Central Europe and Scandinavia during antiquity and into the early Middle Ages. Since the 19th century, they have traditionally been defined by the use of ancient and early medieval Germanic languages and are thus equated at least approximately with Germanic-speaking peoples, although different academic disciplines have their own definitions of what makes someone or something "Germanic". The Romans named the area belonging to North-Central Europe in which Germanic peoples lived Germania, stretching east to west between the Vistula and Rhine rivers and north to south from southern Scandinavia to the upper Danube. In discussions of the Roman period, the Germanic peoples are sometimes referred to as Germani or ancient Germans, although many scholars consider the second term problematic since it suggests identity with present-day Germans. The very concept of "Germanic peoples" has become the subject of controversy among contemporary scholars. Some scholars call for its total abandonment as a modern construct since lumping "Germanic peoples" together implies a common group identity for which there is little evidence. Other scholars have defended the term's continued use and argue that a common Germanic language allows one to speak of "Germanic peoples", regardless of whether these ancient and medieval peoples saw themselves as having a common identity. While several historians and archaeologists continue to use the term "Germanic peoples" to refer to historical people groups from the 1st to 4th centuries CE, the term is no longer used by most historians and archaeologists for the period around the Fall of the Roman Empire and the Early Middle Ages.
