The Mikea Forest (or Forêt des Mikea) is a forested region of southwestern Madagascar, between Manombo and Morombe. More specifically, it stretches from Route Nationale 9 to the west coast and from Mangoky south to the Manombo River. It lies at the transition between dry deciduous forest, which is more common further north in Madagascar, and spiny forest, which is dominant in southwestern Madagascar. Its underlying geology is unconsolidated sand, and the region contains several freshwater lakes. The Forêt des Mikea is one of the largest remaining continuous forest blocks in western and southern Madagascar, but it is not protected and it is threatened by human development.
