Ailanthus altissima /eɪˈlænθəs ælˈtɪsɪmə/ ay-LAN-thəss al-TIH-sim-ə,^[3] commonly known as tree of heaven, Ailanthus, varnish tree, copal tree, stinking sumac, Chinese sumac, paradise tree,^[4] or in Chinese as chouchun (Chinese: 臭椿; pinyin: chòuchūn), is a deciduous tree in the family Simaroubaceae.^[1] It is native to northeast and central China, and Taiwan. Unlike other members of the genus Ailanthus, it is found in temperate climates rather than the tropics.

The tree grows rapidly, and is capable of reaching heights of 15 metres (50 ft) in 25 years. While the species rarely lives more than 50 years, some specimens exceed 100 years of age.^[5] Its suckering ability allows this tree to clone itself indefinitely.^[6] It is considered a noxious weed and vigorous invasive species,^[1] and one of the worst invasive plant species in Europe and North America.^[7] In 21st-century North America, the invasiveness of the species has been compounded by its role in the life cycle of the also destructive and invasive spotted lanternfly.^[8]^[9]
