The Reeves's muntjac (Muntiacus reevesi; Chinese: 山羌) is a muntjac species found widely in southeastern China (from Gansu to Yunnan) and Taiwan. It has also been introduced in Belgium, the Netherlands, the United Kingdom (south England, the Midlands, east Wales), Ireland, and Japan. It takes its name from John Reeves, an employee of the British East India Company in the 19th century.
