The Nalu, also called Nalo, Nanum, or Nanu,[2] are a West African ethnic group who are found in Guinea and Guinea Bissau. They speak the Nalu language. They have been described as "pre-Mandingas", as they settled in the region before the arrival of the Mandé peoples.[3] In this respect Walter Rodney places them alongside the Landuma people, the Baga people, and the Temne people.[3]
The Simo is a West African secret society which is active amongst the Nalu and related people.[4]
