Eremophila viscida, commonly known as varnish bush, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia.

Eremophila viscida is a shrub or tree which grows to a height of between 2 and 6 m (7 and 20 ft) with new growth that is sticky due to the presence of resin.

Flowering occurs between September and November and is followed by fruit which are dry, woody, oval-shaped, 5–7.5 mm (0.2–0.3 in) long and half-covered with simple and glandular hairs.

[2][3][4] The species was first formally described by Stephan Endlicher in 1838 and the description was published in Stirpium Australasicarum Herbarii Hugeliani Decades Tres.

[7] Varnish bush grows in granitic soils in shrubland on salt lake margins, sandplains and stony gullies between Warralakin and Mullewa[3][5] in the Avon Wheatbelt, Coolgardie and Yalgoo biogeographic regions.
