Weyns duiker (Cephalophus weynsi), is a tiny antelope found in the Democratic Republic of Congo, Uganda, and western Kenya. It is sometimes spelled "Weyn's", or as "Weyns' duiker".
Weyns duikers average about 33 pounds (15 kilogrammes) in weight when full grown, with a shoulder height of about 17 inches (43 centimetres). They have a plain rufous coat.
The duiker makes it home in lowlands and montane rainforests.
