Chorizema rhombeum is a species of flowering plant in the family Fabaceae and is endemic to the southwest of Western Australia.

It is a prostrate to ascending or twining shrub with egg-shaped or rhombic leaves, and orange to pink, or red and yellow pea flowers.

[2][3] Chorizema rhombeum was first formally described in 1811 by Robert Brown in William Aiton's Hortus Kewensis.

[4][5] The specific epithet (rhombeum) means "rhombus", referring to the shape of the leaves.

[6] Chorizema rhombeum grows on gentle slopes, river banks and on exposed coastal sites from about Perth to the Stirling Range in the Esperance Plains, Jarrah Forest, Swan Coastal Plain and Warren bioregions of south-western Western Australia.
