Persoonia bargoensis, commonly known as the Bargo geebung,[1] is a species of flowering plant in the family Proteaceae and is endemic to a restricted area of New South Wales.

[1][3][4][5][6] Persoonia bargoensis was first formally described in 1991 by Peter Weston and Lawrie Johnson of the National Herbarium of New South Wales from material collected near Douglas Park in 1989.

[8] Bargo geebung is found in small scattered patches in an area bordered by Picton and Douglas Park to the north, Yanderra to the south, Cataract River to the east and Thirlmere to the west[1] where it grows on Sydney sandstone and Wianamatta shale soils, 100–300 m (330–980 ft) above sea level.

[3] It grows in dry sclerophyll eucalypt forest, under forest red gum (Eucalyptus tereticornis) and broad-leaved red ironbark (E. fibrosa) with a grassy understory of kangaroo grass (Themeda triandra), or more open woodland with such trees as red bloodwood (Corymbia gummifera), scribbly gum (Eucalyptus sclerophylla), grey gum (E. punctata), narrow-leaved stringybark (E. sparsifolia) and small-leaved apple (Angophora bakeri) with a shrubby understory of plants such as wreath bush-pea (Pultenaea tuberculata).

The main threats to the species include its small population size, habitat loss and fragmentation and inappropriate maintenance activities.
