Eckhardt Rehberg (born 3 April 1954) is a German politician of the Christian Democratic Union (CDU) who served as a member of the Bundestag from the state of Mecklenburg-Vorpommern from 2005 until 2021.

In the negotiations to form Merkel's fourth coalition government following the 2017 federal elections, Rehberg was part of the working group on financial policies and taxes, led by Peter Altmaier, Andreas Scheuer and Olaf Scholz.

Amid the economic downturn due to the COVID-19 pandemic in Germany, he demanded that “suspending the debt brake must not become a habit.

We have to get back to the regular debt limit as quickly as possible.”[7] In 2018, Rehberg rejected plans presented by Minister of Finance Olaf Scholz for a European unemployment stabilization fund designed to arm the eurozone against crises.
