Amentotaxus is a genus of conifers (catkin-yews) comprising five species, treated in either the Cephalotaxaceae, or in the Taxaceae when that family is considered in a broad sense.

The genus is endemic to subtropical Southeast Asia, from Taiwan west across southern China to Assam in the eastern Himalaya, and south to Vietnam.

The leaves are spirally arranged on the shoots, but twisted at the base to lie in two flat ranks (except on erect leading shoots); they are linear-lanceolate, 4–12 cm long and 6–10 mm broad, soft in texture, with a blunt tip, green above, and with two conspicuous white stomatal bands below.

The male (pollen) cones are catkin-like, 3–15 cm long, grouped in clusters of two to six together produced from a single bud.

The oldest fossils that are recognisable to the genus are from the Middle-Late Jurassic Daohugou Bed of China.
