Ostrearia is a monotypic genus - i.e. a genus containing only one species - of plants in the witch-hazel family Hamamelidaceae. It is the first described of three monotypic Australian genera in this family, the others being Neostrearia and Noahdendron. It is most closely related to these genera, as well as Trichocladus (4 species) from southern Africa and Dicoryphe (13 species) from Madagascar, and together these five genera form a distinct clade within Hamamelidaceae.
