The Bundesliga is the highest level of Germany's football league system. The term Bundesliga also applies to football in Austria and is used to refer to the highest level league competitions in several other sports in those two countries.

Germany was unusual, in that, unlike in other countries, a unified national league structure was quite late in developing. The Bundesliga was not formed until 1963 and the structure and organisation of the nation's football leagues have undergone frequent changes right up to the present day.
