Lake Retba or Lac Rose lies north of the Cap Vert peninsula of Senegal, north east of Dakar.

It is so named for its pink waters, particularly visible during the dry season. The lake is also known for its high salt content, which, like that of the Dead Sea, allows people to float easily. The lake also has a small salt collecting industry and is often the finishing point of the Dakar Rally.
