Darwinia thymoides is a species of flowering plant in the myrtle family Myrtaceae and is endemic to the south-west of Western Australia.

It is a low, spreading to prostrate shrub with linear to lance-shaped leaves and groups of 4 to 8 green, red or white flowers surrounded by leaf-like bracts.

The flowers are arranged on the ends of branches in sessile groups of 4 to 8, surrounded by leaf-like bracts and short, broad bracteoles that fall off early.

The sepals are thin, 4–6 mm (0.16–0.24 in) long and glabrous but with 5 longitudinal ridges and the petals are green, red or white with a curved style that is bearded at first.

[7] Darwinia thymoides grows on granite outcrops and along creeks in sandy to loam or clay soils in the Avon Wheatbelt, Jarrah Forest, Swan Coastal Plain and Warren bioregions of south-western Western Australia.
