Hibiscadelphus is a genus of flowering plants that are endemic to Hawaiʻi. It is known by the Native Hawaiians as hau kuahiwi which means "mountain Hibiscus". The Latin name Hibiscadelphus means "brother of Hibiscus". It is distinctive for its peculiar flowers, which do not fully open. Hibiscadelphus is in the family Malvaceae, subfamily Malvoideae. Several of the species in this small genus are presumed extinct.
Hibiscadelphus distans is an extremely rare species of flowering plant in the mallow family, Malvaceae, that is endemic to the island of Kauaʻi in Hawaii. It is known as hau kuahiwi in Hawaiian, which means "upland Hibiscus tiliaceus." It is a bush or small tree with heart-shaped leaves and yellow flowers and grows at between 1,000 and 1,800 feet in the remnants of native dry forests. Despite its rarity, it is believed to be the only surviving species in the genus Hibiscadelphus which is only known from Hawaii, the other five species having recently become extinct in the wild, some being known from only a single plant.

Hibiscadelphus giffardianus is a species of flowering plant in the mallow family, Malvaceae, that is endemic to the Big Island of Hawaii. It is believed to be extinct in the wild; any remaining plants are threatened by habitat loss. Cultivated plants exist in Hawaii Volcanoes National Park.

Hibiscadelphus hualalaiensis is a species of flowering plant in the mallow family, Malvaceae, that is endemic to the Big Island of Hawaii. The last known plant died in 1992, making it most likely extinct in the wild; any remaining plants are threatened by habitat loss. It inhabits dry and mixed mesic forests on the slopes of Hualālai at elevations of 915–1,020 m (3,002–3,346 ft). Associated plants include ʻōhiʻa lehua, lama, māmane, naio, ʻālaʻa, pāpala, ʻaiea, poʻolā, and Kikuyu Grass.
