Levenhookia, also known as the styleworts, is a genus of ten recognized species in the family Stylidiaceae and is endemic to Australia. The genus is restricted to Western Australia almost exclusively with a few exceptions: L. pusilla's range extends into South Australia, L. dubia's range extends through South Australia into Victoria and New South Wales, L. sonderi is native only to Victoria, and L. chippendalei is also found in the Northern Territory.

All species of Levenhookia possess a sensitive labellum that performs a similar function to the column of Stylidium species. The labellum responds to touch and enables the plants to promote cross-pollination and avoid self-pollination. Most species of Levenhookia are ephemeral plants that prefer sand heath habitat. Levenhookia species also possess glandular trichomes similar to those of its sister genus, Stylidium. While no studies have been done to test Levenhookia for carnivory, it is plausible that they are carnivorous plants like the related Stylidium species.
