Dagmar Metzger (born 10 December 1958 in Berlin) is a German lawyer and politician, and a former member of the Parliament of Hesse for the Social Democratic Party of Germany (SPD).
She became known to a broader audience in March 2008, when she declared that she would not support Andrea Ypsilanti as Prime Minister of Hesse in the forthcoming election.
Her father-in-law also told journalists that Dagmar Metzger's father, a social democrat from Berlin, under threat of life had opposed the forced unification of SPD and the Communist Party of Germany to form the East German communist party.
In November 2008, Andrea Ypsilanti once again tried to form a government with support of Die Linke, but Metzger and her fellow SPD MPs Silke Tesch, Jürgen Walter and Carmen Everts declared they would not support Ypsilanti as Prime Minister if she formed a government with support of Die Linke, and the election of Ypsilanti as Prime Minister was canceled.
This led to the 2009 Hesse state election in which Dagmar Metzger did not stand as a candidate.
