Leucopogon validus is a species of flowering plant in the heath family Ericaceae and is endemic to a restricted part of the south-west of Western Australia.

It is a robust shrub with glabrous branchlets, narrowly elliptic leaves and white, bell-shaped flowers arranged in six to twelve upper leaf axils and on the ends of branches.

[2][3] Leucopogon validus was first formally described in 2007 by Michael Clyde Hislop and Alex R. Chapman in the journal Nuytsia from specimens collected in the Parker Range south-east of Southern Cross in 2003.

[2] This leucopogon is only known from the Parker Range in the Avon Wheatbelt bioregion of south-west Western Australia, where it grows in open shrubland on breakaways.

[2][3] Leucopogon validus is listed as "Priority One" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[3] meaning that it is known from only one or a few locations that are potentially at risk.
