Fea's muntjac (Muntiacus feae) or the Tenasserim muntjac, is a rare species of muntjac native to southern Myanmar and Thailand. It is a similar size to the common muntjac (adult weight is 18 – 21 kg (40 – 46 lb)).
It is diurnal and solitary, inhabiting upland evergreen, mixed or shrub forest (at an altitude of 2500 m (8200')) with a diet of grasses, low-growing leaves, and tender shoots.
The young are usually born in dense vegetation, remaining hidden until able to travel with the mother.
