M'mah Soumah (born 10 May 1985 in Conakry) is a Guinean judoka who competed in the women's half-lightweight category.
She picked up a bronze medal in the 52-kg division at the 2004 African Judo Championships in Tunis, Tunisia, and represented her nation Guinea at the 2004 Summer Olympics.
Soumah qualified as a lone female athlete and judoka for the Guinean squad in the women's half-lightweight class (52 kg) at the 2004 Summer Olympics in Athens, by granting a tripartite invitation from the International Judo Federation.
She lost her opening match to Portugal's Telma Monteiro, who scored an ippon victory and quickly subdued her on the tatami with a seoi nage (shoulder throw) at eighteen seconds.
