Minna Faßhauer (born Minna Nikolai: 10 October 1875 - 28 July 1949) was a political and feminist activist of the left. Before the First World War she campaigned for gender equality both inside and outside the rapidly growing Social Democratic Party, of which she succeeded in becoming a member in 1903. During the war she was actively engaged in the anti-war Spartacus League. In the revolutionary context of 1918/19 she served as Volkskommissarin für Volksbildung ("People's Commissar for People's Education") in the Socialist Republic of Braunschweig between November 1918 and February 1919, leading admirers to identify her as the first female to serve as a minister in a German regional government.
