Phoebe zhennan is a large species of tree, up to 30 metres (98 ft) tall, in the genus Phoebe of the family Lauraceae. The name "Zhennan" is the transcription of one of the tree's Chinese names, 桢楠. It is endemic to China where it occurs in Guizhou, Hubei, and Sichuan provinces. The species is threatened by habitat loss, and so is under second-class national protection in China. In the past, wood from this tree was so valuable that only royal families could afford their use. Notably, whole logs of Phoebe zhennan wood were used to create pillars for the Forbidden City.
