The Northern red muntjac (Muntiacus vaginalis)[1][2] is a species of muntjac. It is found in numerous countries of south-central and southeast Asia.

It was recently found distinct from the southern red muntjac (previously typically known as Indian muntjac) and includes all the population previously attributed to M. muntjak that are outside of Sunda and perhaps of Malaysia.[1]

The subspecies bancanus, montanus, muntjak, nainggolani, peninsulae, pleiharicus, robinsoni, and rubidus stay in the southern red muntjac (M. muntjak), while annamensis, aureus, curvostylis, grandicornis, and nigripes are now attributed to the northern red muntjac (M. vaginalis).
