Verticordia setacea is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia.

The floral cup is top-shaped, 1.5–2 mm (0.06–0.08 in) long, rough, partly hairy and swollen near the upper end.

[2] Verticordia setacea was first formally described by Alex George in 2010 from a specimen collected on private land near Lake Grace and the description was published in Nuytsia.

[1][2] The specific epithet (setacea) is derived from the Latin word seta meaning "bristle"[3] referring to the bristly surface of some parts of the flowers of this species.

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