Ailanthus (//; derived from ailanto, an Ambonese word probably meaning "tree of the gods" or "tree of heaven") is a genus of trees belonging to the family Simaroubaceae, in the order Sapindales (formerly Rutales or Geraniales). The genus is native from east Asia south to northern Australasia.
The number of living species is disputed, with some authorities accepting up to ten species, while others accept six or fewer. Species include:
- Ailanthus altissima (Mill.) Swingle (Tree of Heaven, syn. A. vilmoriniana Dode) – northern and central mainland China, Taiwan, considered invasive in North America and Britain.
- Ailanthus excelsa Roxb. – India and Sri Lanka
- Ailanthus fordii Noot. – China
- Ailanthus integrifolia Lam. – New Guinea and Queensland, Australia
- Ailanthus triphysa (Dennst.) Alston (White Siris syn. A. malabarica) – northern and eastern Australia.
- Ailanthus vietnamensis H.V.Sam & Noot. – Vietnam
There is a good fossil record of Ailanthus with many species names based on their geographic occurrence, but almost all of these have very similar morphology and have been grouped as a single species among the three species recognized:
- Ailanthus tardensis Hably – From a single locality in Hungary
- Ailanthus confucii Unger – Tertiary period, Europe, Asia, and North America
- Ailanthus gigas Unger – From a single locality in Slovenia
Ailanthus silk moth
A silk spinning moth, the Ailanthus silkmoth (Samia cynthia), lives on Ailanthus leaves, and yields a silk more durable and cheaper than mulberry silk, but inferior to it in fineness and gloss. This moth has been introduced to the eastern United States and is common near many towns; it is about 12 cm across, with angulated wings, and in colour olive brown, with white markings. Other Lepidoptera whose larvae feed on Ailanthus include Endoclita malabaricus.

In line 12 of his poem 'Dry Salvages' T.S.Eliot refers to 'in the rank ailanthus of the April dooryard' alluding to Walt Whitman's poem 'When lilacs last in the dooryard bloom'd' which itself refers to the assassination of Abraham Lincoln.
