Pomaderris crassifolia is a species of flowering plant in the family Rhamnaceae and is endemic to eastern Australia.

It is a shrub with hairy young stems, egg-shaped or elliptic leaves, and clusters of cream-coloured or yellow flowers.

The flowers are borne in clusters or twenty to more than fifty, the clusters 15–50 mm (0.59–1.97 in) long on the ends of branchlets and are cream-coloured and densely hairy.

[2][3] Pomaderris crassifolia was first formally described in 1997 by Neville Grant Walsh and Fiona Coates and the description was published in the journal Muelleria from specimens collected by Paul Irwin Forster in the McPherson Range in 1990.

[2][4] This pomaderris grows in heathland, shrubland and woodland in rocky places on cliffs and mountains mainly near Warwick and in the McPherson Range in Queensland, with a disjunct population near Gloucester in New South Wales.
