The list of justice ministers of Prussia lists the Prussian ministers of justice from the founding of the General Directorate (General-Ober-Finanz-Kriegs-und Domainen-Direktorium) in 1723 until the completion of the federalization (Verreichlichung) of the Prussian justice system during the Gleichschaltung in 1935. The first officeholder was Christoph von Katsch (1723–1729) and the last caretaker of the office was Franz Gürtner (1934–1935).
The office thereby existed during very different political contexts for Prussia: From 1723 until 1806, while Prussia was – at least formally – part of the Holy Roman Empire. From 1806 until 1871 as an office of an independent Kingdom of Prussia. And from 1871 onward as an office of a state of the German Empire (the Free State of Prussia since 1918). The empire itself was a monarchy until its abolition in 1918, before it became the Weimar Republic and finally was transformed into Nazi Germany in 1933.
The German Empire had a separate federal State Secretary of Justice since 1876, who headed the Reichsjustizamt. In 1919 the federal office became known as the Reich Minister of Justice, who headed the Reich Ministry of Justice.
