The Vietnamese sika deer (Cervus nippon pseudaxis) is one of the many subspecies of the sika deer. It is one of the smaller subspecies, due to the tropical environment they live in. They were previously found in northern Vietnam and possibly southwestern China, but have now become extinct in the wild. There are plans for reintroducing this subspecies in the future.
