Ursula Hirschmann (2 September 1913 – 8 January 1991) was a German anti-fascist activist and an advocate of European federalism.

She studied economics at Humboldt University of Berlin, together with her brother Albert O. Hirschman, later a candidate for the Nobel Prize.

In 1932, she joined the youth organization of the Social Democratic Party to participate in the resistance against the advance of the Nazis.

In the summer of 1933, she and her brother moved to Paris, where they became re-acquainted with Eugenio Colorni, a young Italian philosopher and socialist whom they had already met in Berlin.

In 1975, Hirschmann founded the Association Femmes pour l'Europe in Brussels, then in the first days of December of that year, suffered from a cerebral haemorrhage, followed by aphasia, from which she was never to recover completely.
