Dodonaea, commonly known as hop-bushes, is a genus of about 70 species of flowering plants in the soapberry family, Sapindaceae. The genus has a cosmopolitan distribution in tropical, subtropical and warm temperate regions of Africa, the Americas, southern Asia and Australasia, but 59 species are endemic to Australia.

Plants in the genus Dodonaea are shrubs or small trees and often have sticky foliage, with simple or pinnate leaves arranged alternately along the stems. The flowers are male, female or bisexual and are borne in leaf axils or on the ends of branchlets and lack petals. The fruit is an angled or winged capsule.
