Cephalotaxus wilsoniana is a species of coniferous tree in the yew family, Taxaceae. Its common names include Taiwan plum yew, Taiwan cow's-tail pine, and Wilson's plum yew. It is endemic to Taiwan, scattered in montane forests at altitudes of 1,400–2,700 m (4,600–8,900 ft). As Cephalotaxus wilsoniana is dioecious, and grows scattered with broad-leaved trees, the fecundity is not strong. In addition, the seed maturity period is very long. As germination and growth are also slow, Cephalotaxus wilsoniana is not commonly found.

This taxon is sometimes considered to be a variety of Cephalotaxus harringtonii.

This conifer grows up to 9 m (30 ft) tall with drooping branches and reddish-brown flaky bark. It grows in scattered populations in the woodlands of Taiwan. It is sometimes cultivated in local gardens.

The wood of Cephalotaxus wilsoniana is light yellowish brown with dense structure and excellent quality, which can be used for construction, furniture, agricultural appliances. A variety of plant alkaloids can be extracted from leaves, branches, roots and seeds.

• The buds/new branches at the front end of each branch are often three.
• The stomata on the back of the leaf form two light green bands.
• Female inflorescence
• "Naked seed"
