Moustapha Niasse (born 4 November 1939[1]) is a Senegalese politician and diplomat who served as the President of the National Assembly of Senegal from 2012 to 2022.

He was a candidate in the February 2000 presidential election, in which against President Diouf and long-time opposition leader Abdoulaye Wade also competed.

[8] In December 2006, Niasse was chosen as the candidate of Alternative 2007, a coalition of ten opposition parties, for the February 2007 presidential election.

[9] He was briefly detained by police in late January 2007, along with other opposition leaders, after participating in a banned protest regarding the delay of the next parliamentary election until June 2007.

[15] Wade renewed an allegation, previously made in 2002, that Niasse had sold diplomatic passports to Taiwanese businessmen and others from that country.

[16] In the March 2009 local elections, the opposition coalition Benno Siggil Senegaal—which included Niasse and the AFP—performed well in Nioro Department and across the country.

Shortly afterward, Niasse said that Wade should react to his party's poor performance by dissolving the National Assembly and the Senate and resigning as president.

On 30 July 2012, he was elected as President of the National Assembly; he defeated opposition candidate Oumar Sarr, a loyalist of Wade.
