The Hanau City Palace (German: Stadtschloss Hanau) is a former castle and palace in Hanau, Hesse, in Germany. It was the residence palace of the Counts of Hanau and later a secondary residence of the Electors of Hesse. The City Palace was also known as the Old Town Palace (German: Altstädter Schloss) or later as the Electoral Palace (German: Kurfürstliches Schloss).

It developed from a medieval castle complex, which was largely demolished in the 19th century, leaving only a few remnants. During the Second World War, the palace was severely damaged and subsequently mostly torn down, although it could easily have been reconstructed. As a result, only a few auxiliary buildings of the former residence remain today. While there are only sparse sources regarding the appearance of the medieval castle, the various construction phases from the 16th century onwards can be reconstructed from documents and older depictions.
