Katrin Dagmar Göring-Eckardt is a German politician of the German Green Party. Starting her political activity in the now-former German Democratic Republic in the late 1980s, she has been a member of the German Bundestag since 1998. She became co-chair of her party caucus in the Bundestag (2002–2005) and the Greens' Vice President of the Bundestag on 18 October 2005, a position that she held until 2013 and would later reprise in 2021. In the November 2012 primary election, the Green Party chose her and Jürgen Trittin as the top two candidates for the Greens for the 2013 German federal election. She also stood as joint top candidate for the Greens in the 2017 German federal election, alongside Cem Özdemir.

The Bundestag is the German federal parliament. It is the only federal representative body that is directly elected by the German people, comparable to the House of Commons of the United Kingdom. The Bundestag was established by Title III of the Basic Law for the Federal Republic of Germany in 1949 as one of the legislative bodies of Germany and thus it is the historical successor to the earlier Reichstag.
