Hibiscadelphus woodii, or “Wood’s hau kuahiwi”, is a species of flowering plant in the family Malvaceaeendemic to KauaiHawaii. It is a small tree, reaching a height of 2.5–5 m (8.2–16.4 ft).

It was discovered in 1991 and described as a new species in 1995. Only four individuals were found at that time; three of those were crushed by a boulder and died between 1995 and 1998, and the last was found dead in 2011. Pollen was found to be inviable, no fruit set was ever observed and all attempts at propagation, including by cross-pollination with H. distans, failed.It  was later assessed as extinct by the International Union for Conservation of Nature in 2016, but three individuals were rediscovered in 2019 by the National Tropical Botanical Garden. The plants were growing out of a steep cliff and were found using drones
