The Eastern woolly lemur (Avahi laniger), also known as the eastern avahi or Gmelin's woolly lemur, is a species of woolly lemur endemic eastern Madagascar, where it lives in humid forests. This nocturnal primate weighs 1-1.3 kg and reaches a length of 27–29 cm with a tail of 33–37 cm. Its diet consists mainly of leaves and buds.

The eastern woolly lemur lives in monogamous pairs together with their offspring.

Other lemur species that live in the same rainforests of eastern woolly lemur are the diademed sifaka (Propithecus diadema) and the red-bellied lemur (Eulemur rubriventer). In southeastern rainforests, sympatric lemur species of the southern woolly lemur (Avahi meridionalis) are the brown mouse lemur (Microcebus rufus), the greater dwarf lemur (Cheirogaleus major), the fat-tailed dwarf lemur (Cheirogaleus medius) and the collared brown lemur (Eulemur collaris) in Sainte Luce Forest, and the southern lesser bamboo lemur (Hapalemur meridionalis) in Mandena Forest.
