Ricinocarpos speciosus is a species of flowering plant in the family Euphorbiaceae and is endemic to eastern Australia.

Ricinocarpos speciosus is a slender, erect, open monoecious or dioecious shrub that typically grows to height of up to 3 m (9.8 ft), its young branchlets covered with dense, greyish-white, star-shaped hairs.

The lower surface is covered with woolly, soft, white, star-shaped hairs.

[2][3] Ricinocarpos speciosus was first formally described in 1864 by Johannes Müller Argoviensis in the journal Flora: oder Allgemeine Botanischer Zeitung.

[6] This species grows in slopes or on rocky creek banks and rocky slopes of hillsides, in wet sclerophyll forest often near the edges of rainforest, from Tewantin to Springbrook in south-east Queensland, and in Gibraltar Range National Park to near Port Macquarie in New South Wales.
