Hans von der Groeben (14 May 1907 – 6 March 2005) was a German diplomat, lawyer, journalist and member of the European Commission, born in Langheim (today Łankiejmy, Poland) near Rastenburg, East Prussia.

After the state exams, he became a government advisor in 1933 at the Ministry of Nutrition (Reichsernährungsministerium) and in 1937 transferred to his final advisory position for credit and cooperatives (Referats für das Kredit- und Genossenschaftswesen).

Federal Minister for Economic Affairs Ludwig Erhard recruited him from there to work on Germany's response to the Schuman Declaration for better Franco-German relations.

He is responsible for the fact that the EEC received a contractually specified free market framework and found a kindred spirit in the French delegation leader, Robert Marjolin.

The December 1961 adoption of the European antitrust rights is based on his efforts to unite the French and German systems.
