Phebalium laevigatum is a species of erect, slender shrub that is endemic to Western Australia.

The five sepals are about 1.5 mm (0.059 in) long, joined for half their length and covered with rust-coloured scales on the outside.

[2][3][4] Phebalium laevigatum was first formally described in 1998 by Paul G. Wilson in the journal Nuytsia from specimens collected by Nik Donner east of Merredin.

[4][5][6] This phebalium grows in eucalypt scrub and is found between Merredin and the western edge of the Great Victoria Desert.

[2][3] This phebalium is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.
