Thryptomene denticulata is a shrub species in the family Myrtaceae that is endemic to Western Australia.

It generally grows to a width of about 1 metre (3 ft) and has tiny leaves.

[3] It is found on sand plains in the Mid West, Gascoyne and Wheatbelt regions of Western Australia between Shark Bay and Wongan Hills where it grows in sandy soils.

The leaves can be eaten by caterpillars and the plant has a lifespan of five to ten years.

[3] The species was initially described as Scholtzia denticulata in 1864 by the botanist Ferdinand von Mueller in the work Fragmenta Phytographiae Australiae from specimens collected near the Murchison River by Augustus Oldfield.
