Mamadou Ba (born 8 May 1985) is a Senegalese retired footballer who played as a goalkeeper. He earned one cap for the Senegal national team, won the 2010 Senegalese Ligue 1 title with ASC Jaraaf, and also played in the Primeira Liga during a playing career that spanned 13 years and five clubs.
After retiring as a player, Ba remained in Portugal and turned to coaching. In March 2021, he was announced as the goalkeeping coach for Pedras Rubras, competing in the Divisão de Elite of the Porto Football Association. He spent the 2021–22 season in that role on the staff of manager Mário Seara.[1]
Two of Ba's brothers also played professional football: both Abdoulaye and Pape Samba Ba earned caps for the Senegal national team.[2]
