African Socialist Movement (, also known as the MSA) was a political party in French West Africa. The MSA was formed following a meeting of the Section française de l'Internationale ouvrière (SFIO) federations of Cameroon, Chad, the Republic of the Congo, French Sudan (now Mali), Gabon, Guinea, Niger, Oubangui-Chari (now the Central African Republic), and Senegal; the meeting was held in Conakry from January 11 to January 13, 1957. At that meeting it was decided that the African federations would break with its French parent organisation and form the MSA.
