Eremophila warnesii is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia.

There are 5 linear sepals which are 10–15 mm (0.4–0.6 in) long, almost claw-like at the tip and covered with a thick layer of hairs similar to those on the leaves.

Flowering occurs between June and October and is followed by fruit which are cone-shaped to flask-shaped, 6–7 mm (0.2–0.3 in) long with a hairy covering.

[2][3]The species was first formally described by Robert Chinnock in 2007 and the description was published in Eremophila and Allied Genera: A Monograph of the Plant Family Myoporaceae.

[2][3] Eremophila warnesii is classified as "Priority One" by the Western Australian Government Department of Parks and Wildlife,[5] meaning that it is known from only one or a few locations which are potentially at risk.
