Guy-André Kieffer (25 May 1949[1]-c. April 16, 2004) was a journalist of dual French and Canadian nationality who worked in West Africa generally, and in Côte d'Ivoire specifically.

In a 2006 interview regarding her book Bitter Chocolate, CBC journalist Carol Off claimed that Kieffer's disappearance and probable murder was related to his investigation of the shady practices involving the Ivorian government and the cocoa industry.

The French magistrate charged with the case was sent to Abidjan and there interrogated Michel Legré, a brother-in-law of the wife of Ivorian president Laurent Gbagbo, who was allegedly the last person to see Kieffer alive.

[6] On August 23, 2007, French president Nicolas Sarkozy met with Kieffer's wife Osange Silou-Kieffer in Paris and expressed his determination to aid in the case.

[2][3] In July 2008 Simone Gbagbo – First Lady of Côte d'Ivoire – was formally called for questioning by a French investigative judge, examining the April 2004 disappearance and presumed death of Kieffer.

French judicial officials have arrested and are investigating Jean-Tony Oulaï, a former member of the Ivorian Secret Services, whom they detained in Paris in 2006.
