Nikolaus Michael Louis Johann (Hans) von Dallwitz (29 September 1855 in Breslau, Lower Silesia – 2 August 1919 in Bosse) was a politician, who served in Anhalt and Prussia.
In 1902 he became Minister of State for Anhalt and in 1901, Superior President of the province of Silesia.
After a conflict with his conservative colleagues, he resigned from the post (see Saverne Affair).
In 1914 Dallwitz, was chosen by Kaiser Wilhelm II as successor to Count Karl von Wedel as reichsstatthalter of Alsace-Lorraine.
However, the outbreak of the First World War and the subsequent conflict between the populations of Alsace-Lorraine and Prussia led to the resignation of Dallwitz on 14 October 1918.
