Homoranthus tricolor, is a flowering plant in the family Myrtaceae and is endemic to a small area in south-east Queensland.

It is an upright shrub with linear to lance-shaped leaves and green, red and black flowers arranged singly or in pairs in upper leaf axils.

It has grey, slightly lined, fibrous bark near the base of older plants.

The pendulous, cylindrical shaped flowers have elliptic-shaped dark purple to black petals near the base, light green on the margins and toward the apex.

[2][3] Homoranthus tricolor was first formally described in 2009 by Anthony Bean from a specimen he collected south-west of Mundubbera in 2008.
