Lasiopetalum parvuliflorum is a species of flowering plant in the family Malvaceae and is endemic to the south-west of Western Australia.

It is an erect, spreading shrub with hairy stems, oblong to linear leaves and green or cream-coloured flowers.

[2][3] Lasiopetalum parvuliflorum was first formally described in 1868 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae from specimens collected by James Drummond.

[5] This lasiopetalum grows near creeks and in winter-wet areas in the Esperance Plains and Mallee biogeographic region of south-western Western Australia.

[2][6] Lasiopetalum parvuliflorum is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[2] meaning that it is poorly known and known from only a few locations but is not under imminent threat.
