Verticordia cunninghamii, commonly known as tree featherflower or liandu, is a flowering plant in the myrtle family, Myrtaceae and is endemic to an area in the extreme north of Western Australia and the Northern Territory.

Verticordia cunninghamii is a spindly to bushy, openly branched shrub or tree which grows to a height of up to 7 m (20 ft) and which has one to a few thick woody trunks at the base.

The leaves are arranged in opposite pairs along the branches and are linear in shape, roughly round or three-sided in cross section, 10–20 mm (0.4–0.8 in) long, have a pointed tip and prominent oil glands.

[1][4] The specific epithet (cunninghamii) honours Allan Cunningham, who gathered the type collection at Roe River in the Kimberley region on the 14 December 1820.

The species is usually associated with areas of seasonal flooding and watercourses, or along creeks, and has a preference for loam or gravel at exposed sandstone, growing in the white, or grey, or red sands there.
