Eremophila crassifolia, commonly known as thick-leaved emubush or trim emubush, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to an area extending from New South Wales through Victoria to southern parts of South Australia.

Eremophila crassifolia is a low shrub with erect or spreading branches growing to a height and width of up to 1.0 m (40 in) and which often forms root suckers.

[2][3] The species was first formally described by Ferdinand von Mueller in 1859 and the description was published in Papers and Proceedings of the Royal Society of Tasmania.
