Ellen Aurora Ammann (1 July 1870 – 23 November 1932) was a German politician and activist of Swedish origin, a representative of the Bavarian People's Party.

In January 1923, together with Anita Augspurg, Lida Gustava Heymann and a delegation of women, Amman called for Austrian-born Adolf Hitler to be expelled from Germany.

During the Beer Hall Putsch, she and several members of government hastily composed a condemnation of the attempted coup d'état.

Two years later, with the support of Countess Christiane von Preysing-Lichtenegg-Moos, she founded the first Catholic station mission in Munich, which she led for more than two decades.

The educational institution founded by Ellen Ammann was one of the first programmatic training centers for social work in Germany.

Her daughter Maria Ammann headed the social women's school from 1929 to 1961, which was integrated into what is now the Catholic University of Applied Sciences in Munich in July 1970.

In 1914, Ellen Amman was awarded the papal order Pro Ecclesia et Pontifice for her social and charitable commitment.

Immediately after a speech in Parliament about help for large families, Ellen Ammann died in Munich during 1932 in the aftermath of a stroke.
