The Hainan black-crested gibbon (Nomascus hainanus), also called the Hainan gibbon, is a Critically Endangered species of gibbon found only on Hainan Island, in the South China Sea.

It was formerly considered a subspecies of the eastern black crested gibbon (N. nasutus) from Hòa Bình and Cao Bằng provinces of Vietnam and Jingxi County in Guangxi Zhuang Autonomous Region, China. Molecular data, together with morphology and call differences, suggest it is a separate species. Its habitat consists of broad-leaved forests and semi-deciduous monsoon forests. It feeds on ripe, sugar-rich fruit, such as figs and, at times, leaves, and insects.
