The Grand Duchy of Frankfurt was a German satellite state of Napoleonic creation. It came into existence in 1810 through the combination of the former territories of the Archbishopric of Mainz along with the Free City of Frankfurt itself.

Frankfurt lost its status as a free imperial city in 1806 with the dissolution of the Holy Roman Empire. The city was granted to the previous Archbishop of Mainz, Karl Theodor Anton Maria von Dalberg, and became the Principality of Frankfurt. When Dalberg was forced to relinquish his Principality of Regensburg to the Kingdom of Bavaria in 1810, he combined his remaining territories of Aschaffenburg, Wetzlar, Fulda, Hanau, and Frankfurt into the new Grand Duchy of Frankfurt.

Although the grand duchy was named after the city of Frankfurt, Dalberg resided in the city of Aschaffenburg. However, the territory was ruled by French commissioners. By the constitution of the grand duchy, upon Dalberg's death, the state would be inherited by Napoleon's stepson, Eugène de Beauharnais.

Dalberg abdicated in favour of Eugene on 26 October 1813, following Napoleon's defeat at the Battle of Leipzig. The grand duchy ceased to exist after December 1813, when the city was occupied by allied troops. While Frankfurt itself once again became a free city, most of the territory of the grand duchy was ultimately annexed by the Kingdom of Bavaria.
