The Lex Baiuvariorum was a collection of the tribal laws of the Bavarii of the sixth through eighth centuries. The first compilation was edited by Eberswind, first abbot of Niederaltaich, in 741 or 743. Duke Odilo, founder supplemented the code around 748. It is one of the most well documented bodies of Germanic tribal law.

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.
