Thomas Heilmann (born 16 July 1964) is a German politician of the Christian Democratic Union (CDU). Born in Dortmund, North Rhine-Westphalia, he has served as a member of the Bundestag from the state of Berlin since 2017.

From 2001 until 2008, Heilmann was a partner and CEO of Scholz & Friends. In 2001, he was nominated to join the supervisory board of Axel Springer SE; however, he was replaced by Axel Sven Springer before the vote.

At the request of Federal Minister of Labour and Social Affairs Ursula von der Leyen, Heilmann negotiated a high-profile agreement between investor Nicolas Berggruen and other shareholders on the sale of embattled department house chain Karstadt in 2010.

From 2011 until 2012, Heilmann briefly served as chair of the board at Save the Children Germany.

From 2012 until 2016, Heilmann served as State Minister of Justice and Consumer Protection in the coalition governments of successive Governing Mayors of Berlin Klaus Wowereit (2012–2014) and Michael Müller (2014–2016).

In 2012, Heilmann – together fellow state ministers Mario Czaja and Frank Henkel – unsuccessfully advocated for a reduction in the penalty-free personal use of cannabis from 15 to six grams.

In the negotiations to form a Grand Coalition of Chancellor Angela Merkel's Christian Democrats (CDU together with the Bavarian CSU) and the Social Democrats (SPD) following the 2013 German elections, Heilmann was part of the CDU/CSU delegation in the working group on digital policy, led by Dorothee Bär and Brigitte Zypries.

In the 2016 state elections, Heilmann unsuccessfully ran for a seat in the State Parliament.
