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.

Federal elections were held on 22 September to elect the members of the 18th Bundestag of Germany. At stake were all 598 seats to the Bundestag, plus 33 overhang seats determined thereafter. The Christian Democratic Union of Germany/Christian Social Union of Bavaria (CDU/CSU) of incumbent chancellor Angela Merkel won their best result since 1990 with nearly 42% of the vote and nearly 50% of the seats, just five short for an overall majority. The Free Democratic Party (FDP) failed to meet the 5% vote electoral threshold in what was their worst showing ever in a federal election, denying them seats in the Bundestag for the first time in their history.
