The German Formula Three Championship was the national Formula Three championship of Germany, and the former West Germany, from 1950 to 2002, then as Formel 3 until 2014. In 2003, the series had merged with the French Formula Three Championship to form the Formula 3 Euro Series. The lower-level series, the ATS Formel 3 Cup, subsequently operated in Germany, but it folded after the end of the 2014 season. Since the late 1980s, the list of German F3 champions has included many notable drivers, including Formula One World Champion Michael Schumacher and nine-time Le Mans winner Tom Kristensen.

Formula Three, also called Formula 3, abbreviated as F3, is a third-tier class of open-wheel formula racing. The various championships held in Europe, Australia, South America and Asia form an important step for many prospective Formula One drivers.
