Thryptomene biseriata is a species of flowering plant in the family Myrtaceae and is endemic to arid areas of southern central Australia.

It is an erect, multi-stemmed shrub with more or less round to club-shaped leaves and pink flowers with five petals and five stamens.

[2][3] Thryptomene biseriata was first formally described in 1986 by John Green in the Flora of South Australia from specimens collected by Alex George, 25.7 km (16.0 mi) north of Cundeelee in 1963.

[4] The specific epithet (biseriata) means "arranged in two rows", referring to the sepals and petals.

[2][3] Thryptomene biseriata is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
