Persoonia chamaepitys, commonly known as the prostrate- or mountain geebung,[1] is a shrub endemic to New South Wales in eastern Australia.

It has a prostrate habit, reaching only 20 cm (7.9 in) high but spreading up to 2 m (6.6 ft) across, with bright green spine-like leaves and small yellow flowers appearing in summer and autumn.

[1] In 1870, George Bentham published the first infrageneric arrangement of Persoonia in Volume 5 of his landmark Flora Australiensis.

It grows at an altitude of 360 to 1,100 m (1,180 to 3,610 ft), on sandstone-based soils in heath or dry sclerophyll forest.

It makes an attractive rockery plant, its bright green foliage and yellow flowers are features.
