Gaudium blakelyi is a species of shrub that is endemic to rocky clifftops near Lithgow in New South Wales.

It has densely silky young stems, egg-shaped to elliptical leaves and white or pink flowers.

Gaudium blakelyi is a spreading shrub that typically grows to a height of 1 m (3 ft 3 in) and has closely adhering flakes of bark that is shed in fibrous strips.

[3][4] In 2023, Peter Gordon Wilson transferred the species to the genus Gaudium as G. blakelyi in the journal Taxon.

[1][5] The specific epithet (blakelyi) honours William Blakely who wrote an unpublished description of this species.
