Winfried Hermann (born 19 July 1952 in Rottenburg am Neckar) is a German politician of Alliance '90/The Greens.

[1] After high school diploma Hermann studied German Philology, Political Science and Sports at the University of Tübingen.

[2][3] From 1992 until 1997, Hermann served as co-chair of the Green Party in Baden-Württemberg, alongside Dagmar Dehmer (1992–1993) and Barbara Graf (1995–1997).

[1] While still in parliament, Hermann joined Gerhard Schick, Hans-Christian Ströbele and Anton Hofreiter in their successful 2011 constitutional complaint against the refusal of Chancellor Angela Merkel’s government to provide information on the Deutsche Bahn and financial market supervision.

In its judgment pronounced in 2017, the Federal Constitutional Court held that the government had indeed failed to fulfil its duty to give answers in response to parliamentary queries and to sufficiently substantiating the reasons.
