The Serer (also spelled Serreer, Sereer, Sèrèr, Sérér, Seréer, Sèréer, Séréer, etc.) are the second largest ethnic group in Senegal and are a major group in The Gambia. Their traditional kingdoms include the Kingdom of Sine and Saloum. They are divided into several groups that speak mutually-unintelligible languages:
- Serer-Sine spoken in Sine-Saloum, Kaolack, Diourbel, Dakar and many other areas.
- Serer-Safen spoken southeast of Dakar inland from the Petit Cote.
- Serer-Ndut spoken in the Mont-Roland area northwest of Thies.
- Serer-Noon spoken around Thies.
- Serer-Palor spoken in a small area between Rufisque and Thies.
- Serer-Lehar spoken in a small area north of Thies.
Historically, the Serer believe that they migrated to central Senegal from the North in the 10th to 13th centuries.
