Coquerel's giant mouse lemur (Mirza coquereli), also known as Coquerel's dwarf lemur or the southern giant mouse lemur, is a small nocturnal lemur endemic to Madagascar. This species can be found in parts of the Madagascar dry deciduous forests.

This species is active throughout the year, unlike mouse lemurs (Microcebus), it does not hibernate. It feeds on the larvae of hemiptera (the true bugs) to sustain itself. It is an arboreal species, and feeds on fruit, flowers, and small animals such as insects and spiders. Coquerel's giant mouse lemur is heavily preyed upon by owls.
