Homoranthus clarksonii is a flowering plant in the family Myrtaceae and is endemic to a small area in Queensland.

It is an upright shrub with pointed, linear leaves and pairs of creamy pink to pale yellow flowers which turn pink as they age.

[2] Homoranthus clarksonii was first formally described in 2011 by Lachlan Copeland, Lyndley Craven and Jeremy Bruhl from a specimen collected on Mount Mulligan in 2001 and the description was published in Australian Systematic Botany.

[3] The specific epithet (clarksonii) honours John Richard Clarkson who discovered the species.

[2] Homoranthus clarksonii grows in shallow, sandy soils amongst sandstone boulders on the north western edge of Atherton Tablelands west of Mareeba.
