Gisèle Mendy (born 19 December 1979) is a Senegalese judoka, who played for the middleweight category.

[5][6] Mendy represented Senegal at the 2008 Summer Olympics in Beijing, where she competed for the women's 70 kg class.

She lost the first preliminary round match, by an ippon (full point) and a te gatame (hand armlock), to German judoka and Olympic bronze medalist Annett Böhm.

[7] Because her opponent advanced further into the semi-finals, Mendy offered another shot for the bronze medal by entering the repechage rounds.

Unfortunately, she was defeated in her first match by Ukraine's Nataliya Smal, who successfully scored a waza-ari-awasete-ippon (full point) and a kuchiki taoshi (single leg takedown), at fifty-two seconds.
