Homoranthus tropicus is a flowering plant in the family Myrtaceae and is endemic to tropical north Queensland.

It is a shrub with curved, club-shaped leaves and white flowers in a corymb-like arrangement on the ends of branchlets.

Flowering occurs sporadically throughout the year, primarily February to July and the fruit is a single seed retained in the calyx.

[2][3] Homoranthus tropicus was first formally described in 1981 by Norman Byrnes from a specimen he collected north of Laura in 1975 and the description was published in Austrolbaileya.

[5] This species grows in northern Queensland in heath or shrubby woodland on shallow rocky soils over sandstone.
