The death toll was confirmed by the Sports Minister, Matar Ba.
Those killed died in a stampede at a soccer stadium in the Senegalese capital Dakar during a match between two local teams.
A fight broke out between fans of rivals US Ouakam and Stade de Mbour while police fired tear gas to break it up.
The resulting confusion triggered the stampede.
Deadly stampedes at soccer matches have been common in Africa, where safety standards are low.
At least 17 people died and scores were injured in a stampede in a match in Angola in February, when hundreds of supporters stormed the stadium.
