Ranunculus pimpinellifolius, commonly known as bog buttercup, is a flowering plant in the family Ranunculaceae and grows in eastern Australia.

[2] Ranunculus pimpinellifolius is a perennial herb covered with soft, weak hairs or almost smooth.

The leaves are mostly at the base of the stems, pinnately divided into 3-7 segments, segments usually with three lobes and rounded teeth, oval to oblong-shaped, 1–5 cm (0.39–1.97 in) long on a petiole 2–12 cm (0.79–4.72 in) long and sparse to thickly covered in spreading hairs.

[2][3][4] Ranunculus pimpinellifolius was first formally described in 1834 by William Jackson Hooker and the description was published in The Journal of Botany.

[5] Bog buttercup grows in boggy locations, wet grasslands and herbfields at higher altitudes in New South Wales, Victoria, Tasmania and the Australian Capital Territory.
