Camptotheca (happy tree) is a genus of medium-sized deciduous trees growing to 20 m tall, native to central China. They are usually included in the tupelo family Nyssaceae, but sometimes included (with the tupelos) in the dogwood family Cornaceae.

There are two species:

  • Camptotheca acuminata Decne.
  • Camptotheca lowreyana S.Y.Li

The name 'happy tree' is a direct translation of the Chinese name xi shu. An extract from the tree (camptothecin) is used as an anti-cancer treatment in China.
