Wahlenbergia queenslandica is a small herbaceous plant in the family Campanulaceae native to Western Australia,[3] to New South Wales, Queensland, the Northern Territory, and South Australia.

[4] The straggling to erect to ascending perennial herb typically grows to a height of 0.3 to 1.0 metre (1 to 3 ft).

It blooms between April and September producing blue-purple flowers in WA.

[4] It is similar to W. communis: both have large corollas with long lobes, however W. communis differs in having a strictly alternate leaf arrangement, long hairs on the inner surface of the corolla tube near the base, and obconical (and frequently more elongated) fruit.

[5] The species is found on the edges of swamps and creek beds and damp flats in the Kimberley region of Western Australia where it grows in sandy-loam soils.
