Pinus massoniana (English: Masson's pine, Chinese red pine, horsetail pine; Chinese: 马尾松) is a species of pine, native to a wide area of central and southern China, including Hong Kong and Taiwan, and northern Vietnam, growing at low to moderate altitudes, mostly below 1,500 m but rarely up to 2,000 m altitude.
It is an evergreen tree reaching 25–45 m in height, with a broad, rounded crown of long branches. The bark is thick, greyish-brown, and scaly plated at the base of the trunk, and orange-red, thin, and flaking higher on the trunk. The leaves are needle-like, dark green, with two per fascicle, 12–20 cm long and 0.8–1 mm wide, the persistent fascicle sheath 1.5–2 cm long. The cones are ovoid, 4–7 cm long, chestnut-brown, opening when mature in late winter to 4–6 cm broad. The seeds are winged, 4–6 mm long with a 10–15 mm wing. Pollination is in mid spring, with the cones maturing 18–20 months after.
The species is a common trees in plantation forestry for replacing or compensating of the loss of the natural forest in southern China. Chinese rosin is obtained mainly from the turpentine of this pine (Pinus massoniana) and slash pine (P. elliottii).
Logs are mainly used to make pulp for paper industry.
