Conothamnus aureus is a member of the family Myrtaceae and is endemic to Western Australia.

It is a spindly, straggly shrub with rigid, blunt leaves and spherical heads of golden yellow flowers resembling those of wattles.

The flowers are golden yellow and arranged on the ends of branchlets in spherical heads about 10 mm (0.4 in) in diameter.

[7] The specific epithet (aureus) is a Latin word meaning "golden".

[8] Conothamnus aureus is found on sand plains, flats and sand dunes in an area along the south coast from the Stirling Range east to Israelite Bay, extending from the Great Southern and into the south western Goldfields-Esperance regions of Western Australia where it grows in sandy or loamy soils.
