'''''Thomasia rulingioides''''' is a species of flowering plant in the family Malvaceae and is endemic to the south-west of Western Australia. It is an erect, open shrub with densely hairy new growth, narrowly oblong to narrowly egg-shaped leaves with wavy edges, and pink to purple flowers.

==Description== ''Thomasia rulingioides'' is an erect, open shrub that typically grows to {{cvt|15–65|cm}} high and {{cvt|50–80|cm}} wide and has its young growth densely covered with star-shaped hairs. The leaves are narrowly oblong to narrowly egg-shaped, {{cvt|5–30|mm}} long and {{cvt|3–10|mm}} wide on a petiole {{cvt|1–2|mm}} long with the edges wavy and rolled under. There are stipules at the base of the petiole, but are soon shed. Both surfaces of the leaves are covered with star-shaped hairs, more densely and paler on the lower surface. The flowers are about {{cvt|8|mm}} in diameter and arranged in racemes of 2 to 5, each flower on a pedicel about {{cvt|3|mm}} long, with hairy, linear bracteoles {{cvt|3–6|mm}} long at the base. The sepals are pink to purple, joined for about half their length and the petals are tiny.
