The Treaty of Fontainebleau (German: Vertrag von Fontainebleau) was signed on 30 May 1631 during the Thirty Years' War, at the Palace of Fontainebleau. It was a pact of mutual assistance between Maximilian I, Elector of Bavaria, and France, for a period of eight years.
The treaty provides an example of the complex relationships between the various participants. In it, France agreed to protect Maximilian from Gustavus Adolphus of Sweden, also a French ally and opponent of Emperor Ferdinand, Maximilian's overlord.
Attempts to keep it secret proved impossible, but Gustavus' death at Lützen in September 1632 ended Swedish ambitions in Bavaria.
