Hibbertia tomentosa is a species of flowering plant in the family Dilleniaceae and is endemic to the Northern Territory.

It is a small, spreading to low-lying shrub with its foliage covered with rosette-like hairs, and has linear leaves and yellow flowers arranged singly on the ends of short side branches, with fourteen to twenty stamens arranged in bundles around two densely scaly carpels.

Hibbertia tomentosa is a spreading to low-lying shrublet that typically grows to a height of up to 50 cm (20 in) and has foliage covered with rosette-like hairs.

[2] Hibbertia tomentosa was first formally described in 1817 by Augustin Pyramus de Candolle from an unpublished description by Robert Brown.
