Mamadou Seck is a Senegalese politician who was President of the National Assembly of Senegal from 2008 to 2012.

In connection with a case regarding the diversion of proceeds from the sale of food aid, Seck was given a two-year suspended sentence in 1988.

However, his appointment caused attention to be focused on his conviction in the late 1980s,[2] and as a result he promptly resigned from the government on 23 May 2001.

According to Seck, he felt this was necessary due to the nature of the allegations and the doubts some had regarding his moral integrity.

[5] He then became the President of the National Assembly's Finance, General Economy, Planning, and Cooperation Committee.
