Mamoutou N'Diaye (born 15 March 1990) is a Malian professional footballer who plays as a defensive midfielder.
He persuaded Gent in the testing period he passed in Ghent in the winter break of the season 2008–09.
RSC Anderlecht was also interested in N'Diaye, but he chose KAA Gent because he would have too many competitors in Anderlecht, and also because his agent is a good friend of the manager of KAA Gent, Michel Louwagie.
On 2 August 2021, he returned to Belgium and signed a two-year contract with Westerlo.
