Cephalotaxus hainanensis is a species of conifer known by the common name Hainan plum-yew. It is endemic to the island of Hainan in southern China. It is possibly a synonym of Cephalotaxus mannii.
C. hainanensis is suggested to have antileukemia activity, and is widely used as an herbal remedy in China. Exploitation of the bark and leaves is a potential threat to this species. Logging has historically been a cause of its decline, but as logging is no longer allowed on Hainan, much of the pressure is currently from illegal harvesting for Chinese remedies.
