Didier Motchane (17 September 1931 – 29 October 2017) was a French politician who served as a member of the European Parliament from 1979 to 1989.

He was born in Paris on 17 September 1931 to mathematician Léon Motchane.

Didier Motchane later married actress and film director Dominique Cabrera.

He is often credited with the fist and rose design used by socialist political organizations worldwide, which he claimed to have “invented” in his 2010 memoirs,[2] but the initiative is disputed between other party leaders of the time.

He left the party in 1993 after a disagreement with François Mitterrand, and helped establish the Citizen and Republican Movement.
