Kassi (fl. 1341) was an empress of Mali. Principal wife and paternal cousin of Suleyman, Kassi ruled jointly with her husband, as was traditional. She was extremely popular with the royal court, which counted many of her relations among its members. But she soon fell out of favor with her husband, who preferred a commoner named . Eventually, he divorced her to marry the latter. The noble ladies of the court took Kassi's side, continuing to recognize her legitimacy and refusing to honor the new empress. Such insubordination – they threw earth on their heads to honor Kassi while throwing earth on their hands to insult Bendjou – soon angered Suleyman and his new wife, to the point that Kassi was forced to seek sanctuary in the mosque.
