金英属（学名：Thryallis）是金虎尾科下的一个属，为灌木植物。该属共有15种以上，分布于美洲。

Thryallis is a genus in the Malpighiaceae comprising 5 species of scandent shrubs and woody vines native to Brazil and adjacent Paraguay and Bolivia.

At one time some species now assigned to Galphimia, e.g., Galphimia gracilis, were referred to Thryallis, but the generic name Thryallis is now a conserved name according to the rules of the rules of Botanical Nomenclature. The genus Thryallis is distinctive in the stellate hairs and scales found on the vegetative parts, and in that the limb of the petals is much wider than long, traits not found in Galphimia.
