Marie-Luise Dött (née Duhn, born 20 April 1953 in Nordhorn) is a German politician of the Christian Democratic Union (CDU) who served as a member of the Bundestag from 1998 to 2021.

In the negotiations to form a Grand Coalition of the Christian Democrats (CDU together with the Bavarian CSU) and the SPD under the leadership of Chancellor Angela Merkel following the 2013 elections, Dött was part of the CDU/CSU delegation in the working group on the environment and agriculture, led by Katherina Reiche and Ute Vogt.

In similar negotiations following the 2017 federal elections, she was part of the working group on energy, climate protection and the environment, this time led by Armin Laschet, Georg Nüßlein and Barbara Hendricks.

[10] At a discussion event hosted by Paul Friedhoff (FDP), a member of the German Bundestag, at which the controversial physicist Fred Singer also appeared, Dött criticized the climate protection policy of the then-red-green federal government as a "substitute religion" in 2010.

[13] In a later press release, Dött explained that she used the term "substitute religion" to characterize those who try to give climate protection a political primacy and make it the sole yardstick of energy policy.

[17] Since the agreement between the CDU and FDP, Dött has been committed to an accelerated phase-out of nuclear energy, but she emphasized: "We cannot do a head over heels restructuring according to the motto 'cost what it may',"[18][19] thus confirming her position on ambitious climate protection policy based on economic efficiency and social equilibrium.

[21] Under the umbrella of the German parliaments' godparenthood program for human rights activists, Dött has been raising awareness for the work of persecuted Vietnamese lawyer Nguyễn Văn Đài since 2015; he was eventually granted asylum in Germany in 2018.
