Noadendron is a monotypic genus - i.e. a genus containing only one species - of plants in the witch-hazel family Hamamelidaceae. It is the third described of three monotypic Australian genera in this family, the others being Ostrearia and Neostrearia. It is most closely related to these genera, as well as Trichocladus from southern Africa and Dicoryphe from Madagascar, and together these five genera form a distinct clade within Hamamelidaceae.
