Hawaiian hibiscus are seven species of hibiscus native to Hawaii. The yellow hibiscus is Hawaii's state flower. Most commonly grown as ornamental plants in the Hawaiian Islands are the non-native Chinese hibiscus (Hibiscus rosa-sinensis) and its numerous hybrids, though the native Hibiscus arnottianus is occasionally planted.

The native plants in the genus Hibiscus in Hawaii are thought to have derived from four independent colonization events for the five endemic species (four closely related species plus the yellow-flowered species) and one each for the two indigenous species.
