Marie-Madeleine Mborantsuo OEE ONM (born 18 April 1955) is a Gabonaise lawyer who is the former romantic partner of Omar Bongo, the long-standing authoritarian ruler of Gabon.
[1] She is the president of the Constitutional Court of Gabon (Cour Constitutionnelle de la Republique Gabonaise) since its foundation in 1991.
She won a "Miss Franceville" beauty pageant, and became the lover of the then president Omar Bongo, with whom she had two children.
[6] From 1983 to 1991 she was president of the Cour de Comptes of the Supreme Court of Gabon and taught law at Omar Bongo University.
[2] It has been suggested that she "contributed to the Constitutional Court's loss of legitimacy as an impartial institution" by making controversial decisions on the allegedly fraudulent presidential elections of 1993, 2009 and 2016 in which her former lover and then her step-son Ali Bongo Ondimba retained and gained the post of president.
