Boronia pinnata is a plant in the citrus family, Rutaceae, and is endemic to New South Wales.

It is an erect, woody shrub with pinnate leaves and groups of between three and forty pink flowers arranged in leaf axils.

[2][3][4] Boronia pinnata was first formally described in 1798 by James Edward Smith who published the description in his book ''Tracts relating to natural history.

[2] This boronia grows in dry forest and heath on sandstone in near-coastal areas between the Nowra district and Ballina.

[3][4] One of the easier boronias to grow in gardens, B. pinnata does best in a sheltered position with rocks aiding a shallow root run and it benefits from light pruning.
