Mamoutou N'Diaye (born 15 March 1990) is a Malian professional footballer who plays as a defensive midfielder.
N'Diaye is a central midfielder, who also plays as central defender. He persuaded Gent in the testing period he passed in Ghent in the winter break of the season 2008–09. He played his first minutes in the Belgian 1st Division on April 18, 2010, against Zulte-Waregem. He was the substitute of Christophe Lepoint. 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. In the season 2010–2011, Mamoutou has been lent for one year to RAEC Mons.
In January 2019, he joined Romanian club Dinamo București.[1] He scored his first goal for Dinamo on 22 April 2019, in a game against FC Botoșani.[2] He was released by Dinamo in August 2020.
On 2 August 2021, he returned to Belgium and signed a two-year contract with Westerlo.[3]
