Persoonia filiformis is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia.

Description
Persoonia filiformis is an erect shrub that typically grows to a height of 7–40 cm with thin bark and branchlets that are hairy when young. The leaves are arranged alternately, linear in shape, 10–20 mm long and about 1 mm wide with six prominent, parallel veins and a sharp point on the tip. The flowers are arranged singly or in pairs or groups of up to twenty along a rachis up to 30 mm long that grows into a leafy shoot after flowering, each flower on a glabrous pedicel 1–2 mm long. The tepals are greenish yellow, 11–16 mm long and glabrous on the outside with greenish yellow anthers that are fused to the tepals. Flowering occurs from November to December.

Taxonomy
Persoonia filiformis was first formally described in 1994 by Peter Weston in the journal Telopea from specimens he collected near the turnoff to Jurien Bay from the Brand Highway in 1980.
