The genus Cunninghamia is a genus of one or two species of evergreen coniferous trees in the cypress family Cupressaceae. They are native to China, Taiwan, northern Vietnam and Laos, where they may reach 50 m in height. In vernacular use, it is most often known as Cunninghamia, but is also sometimes called "China-fir" (though it is not a fir). The genus name Cunninghamia honours Dr. James Cunningham, a British doctor who introduced this species into cultivation in 1702 and botanist Allan Cunningham.
