Banksia squarrosa, commonly known as pingle,[2] is a species of prickly shrub that is endemic to Western Australia.

Flowering occurs from June to November and the follicles are oblong to egg-shaped, 8–13 mm (0.31–0.51 in) long and more or less glabrous.

[2][3] This species was first collected from near King George Sound in 1829 by William Baxter, and its description was published by Robert Brown in Supplementum primum Prodromi florae Novae Hollandiae as Dryandra squarrosa the following year.

[11][12] Pingle is widely distributed in the south-west of Western Australia, occurring between Bindoon, the Whicher Range and Albany, growing in woodland and forest.

[3] This banksia is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife,[2] but subspecies argillacea is listed as "Threatened Flora (Declared Rare Flora — Extant)" by the Department of Environment and Conservation (Western Australia)[13]
