Kerstin Andreae (born 21 October 1968) is a German politician of Alliance '90/The Greens who served as Member of the Bundestag from 2002 to 2019.

Since leaving politics, she has been serving as managing director of the German Association of Energy and Water Industries (BDEW).

In 2012, she succeeded Fritz Kuhn as the group's deputy chairperson, at the time led by co-chairs Renate Künast and Jürgen Trittin.

After the 2013 federal elections, Andreae — who is considered a centrist in her party[1] — unsuccessfully tried to become the chairwoman of the Green's parliamentary group.

[2] Commentators regarded her loss against Katrin Göring-Eckardt as a sign that Green lawmakers rejected a chance to reach out to Angela Merkel’s CDU as a possible coalition partner.
