Carsten Christoffer Linnemann (born 10 August 1977) is a German economist and politician of the Christian Democratic Union (CDU) who has been a member of the German Bundestag since the 2009 election,^[1] representing Paderborn.

From 2013 until 2021, Linnemann served as the chairman of MIT, the pro-business wing in the CDU/CSU.^[3][4]

Between 2006 and 2007, Linnemann, a devoted Catholic, was an assistant to Norbert Walter, chief economist of Deutsche Bank. He subsequently worked as economist with IKB Deutsche Industriebank from 2007 to 2009, where he focused on small and medium enterprises.

In the negotiations to form a Grand Coalition of the Christian Democrats (CDU together with the Bavarian CSU) and the Social Democrats (SPD) following the 2013 federal elections, Linnemann was part of the CDU/CSU delegation in the working group on labor policy, led by Ursula von der Leyen and Andrea Nahles. In similar talks following the 2017 federal elections, he was again part of the working group on social affairs, this time led Nahles, Karl-Josef Laumann and Barbara Stamm.
