Esperance mallee is an ecoregion on the south coast of Western Australia, a coastal strip where the predominant vegetation consists of short eucalyptus trees and shrubs.

[5] Mallee is a generic term used to describe a number of eucalyptus trees that have an underground bulb called a lignotuber from which new buds can sprout following a forest fire.

Mallee trees and accompanying shrubs are thus adapted to the poor soils, lack of rainfall, and regular fires, something common for the dry coast.

Wildlife of the coast includes the highly venomous common death adder.

Mammals include tiny honey possums (which feed on nectar of the kangaroo paw flowers) and the endangered western quoll.
