Commersonia magniflora is a species of flowering plant in the family Malvaceae and endemic to Australia.

It is an erect shrub with wrinkled, narrowly oblong to elliptic or egg-shaped leaves, and deep pink flowers.

The flowers are 15–20 mm (0.59–0.79 in) wide with five deep pink, petal-like sepals joined for most of their length, and five cream-coloured petals that are much shorter than the sepals, the ligule narrowly oblong.

Flowering occurs from May to December and the fruit is a hairy, elliptic capsule 8 mm (0.31 in) wide.

[2][3][4] This species was first formally described in 1874 by Ferdinand von Mueller who gave it the name Rulingia magniflora in his Fragmenta Phytographiae Australiae,[5][6] but in 1881 he transferred it to the genus, Commersonia in a later edition of Fragmenta Phytographiae Australiae.
