Klaus Lederer (born 21 March 1974) is a German politician of The Left who served as Deputy Mayor and Senator for Culture and Europe in the Berlin state government between December 2016 to April 2023.

Lederer was born in Schwerin and grew up in Frankfurt an der Oder,[1] where he attended Polytechnic Secondary School.

He then worked on his dissertation on Privatization in the water sector at the Law Faculty of Humboldt University, where he received his doctorate in 2004.

In February 2005, Lederer received the Carl Goerdeler Award from the Carl and Anneliese Goerdeler Foundation Leipzig and the Deutsches Institut für Urbanistik for his doctoral thesis, as well as the John Desmond Bernal Award from the Rosa Luxemburg Foundation Brandenburg.

He performed several times with the Prenzlauer Berg-based a cappella group Rostkehlchen and released a CD in 2002, covering songs of the former East German punk band Feeling B in the style of a 1920s tenor.

[2] In December 2005, Lederer succeeded Stefan Liebich as state chairman of the Berlin branch of the PDS, which by this time had been renamed Left Party.PDS.

Lederer subsequently led the Left's negotiations with the SPD and Greens to form a coalition government, which were successful.
