Thryptomene pinifolia is a species of flowering plant in the family Myrtaceae and is endemic to Kalbarri National Park in Western Australia.

It is a shrub with linear leaves, and flowers with pale pinkish sepals and petals and seven or eight stamens.

The flowers are arranged in clusters of two or three pairs near the ends of branchlets on peduncles 0.8–1.3 mm (0.031–0.051 in) long.

[2] Thryptomene pinifolia was first formally described in 2014 by Barbara Lynette Rye and Malcolm Eric Trudgen in the journal Nuytsia from specimens collected near Eurardy in 2000.

[4] Thryptomene pinifolia is classified as "Priority Two" by the Western Australian Government Department of Parks and Wildlife[4] meaning that it is poorly known and from only one or a few locations.
