Acropora hemprichii is a species of acroporid coral that was first described by Christian Gottfried Ehrenberg in 1834. It lives in reefs at depths of 3 to 15 m (9.8 to 49.2 ft) for between 13 and 24 years. The species is listed as endangered on the IUCN Red List, and has a decreasing population. It is common with a wide range, and is listed on Appendix II of CITES.

Description Acropora hemprichii lives in colonies of densely-packed branches, which are flat or upward-facing. Branches grow to diameters of between 12 and 30 millimetres (0.47 and 1.18 in) and lengths of around 80 millimetres (3.1 in). These colonies are often more than 2 m (6.6 ft) wide, and can exist without the presence of any other species. The axial corallites are rounded and shaped like domes, and the incipient axial corallites are present on some specimens. The radial corallites are cone-shaped irregularly spaced, have smooth walls, and are large. It has a smooth coenosteum, and the species is mainly brown or pink-brown. It exists in shallow reefs in marine environments, and at depths of 3 to 15 m (9.8 to 49.2 ft).
