The Montagne d'Ambre dwarf lemur or Andy Sabin's dwarf lemur (Cheirogaleus andysabini), is a species of dwarf lemur known only from Amber Mountain National Park and the surrounding area in northern Madagascar. It was identified in 2005, but not formally described until 2015. Its conservation status has not been determined, but it is at risk from deforestation and possibly hunting from nearby human populations.
