The Kingdom of Sine (also: Sin, Siine or Siin in the Serer-Sine language) is a pre-colonial Serer kingdom along the north bank of the Saloum River delta in modern Senegal.
The inhabitants are called Siin-Siin or Sine-Sine (a Serer plural form or Serer-demonym, e.g. Bawol-Bawol and Saloum-Saloum / Saluum-Saluum, inhabitants of Baol and Saloum respectively).
