Goodenia laevis was first formally described in 1868 by George Bentham in Flora Australiensis from specimens collected by George Maxwell in the "Phillips Ranges". The specific epithet means "smooth".In 1998, Leigh William Sage described two subspecies of G. laevis in the journal Nuytsia and the names are accepted by the Australian Plant Census:Goodenia laevis subsp. humifusa L.W.Sage has a prostrate habit and leaves wide;Goodenis laevis Benth. subsp. laevis has an erect habit and leaves wide.
The name means "lying down", referring to the prostrate habit of this subspecies.
