Marie Seebach (24 February 1829 – 3 August 1897) was a German actress.
She was born in Riga, Livonia, Russian Empire as the daughter of an actor, Wilhelm Friedrich Seebach (1798–1863). After appearing first at Nuremberg as Julie in Kean, she played soubrette parts at Lübeck, Danzig and Cassel. In 1852 she achieved her first great success at the Thaliatheater in Hamburg as Gretchen in Goethe's Faust, and she remained there until 1854, when she appeared in Vienna.
In Hanover, in 1859, she married the tenor Albert Niemann. In 1866 she followed her husband to Berlin, but separated from him after two years.
In 1870–1871 she visited the United States, and gave in seventeen cities no less than 160 performances mostly of Faust; and in 1886 she accepted a permanent engagement at the Schauspielhaus in Berlin. In 1895 she endowed a home for poor actors and actresses at Weimar, called the Marie Seebach Stiftung.
She retired from the stage in 1897, and died on 3 August of that year.
