Pinus yunnanensis, the Yunnan pine, is a species of conifer in the family Pinaceae. It is found in the Chinese provinces of Yunnan, Sichuan, Guizhou, and Guangxi.
Pinus yunnanensis can grow up to 30 m (98 feet) in height and 1 m (3 ft 3in) in trunk diameter when mature. The bark is rough when young, becoming scaly, fissured, and longitudinally fissured with age; gray-brown weathering to gray. The habit of a mature tree is a single, sometimes forked trunk, with spreading or down curving branches forming a domed or flat-topped crown.
