Acropora caroliniana is a species of acroporid coral that was first described by Nemenzo in 1976. Found in tropical, shallow reef slopes, it occurs at depths of 5 to 25 m (16 to 82 ft) in a marine environment. The species is rated as vulnerable on the IUCN Red List, with a decreasing population. It is rare, but has been found over a large area, and two-thirds of the regions of Indonesia.

Description Acropora caroliniana species form in thick horizontal structures, made of flat branches. It is light green, pale blue or white-brown in colour, and are also found on small branchlets. These have large axial corallites with diameters up to 1.7 to 3.5 millimetres (0.067 to 0.138 in) which become narrow at the ends, and curve upwards. The species' radial corallites are small and "pocket-like". It looks similar to Acropora lokani and Acropora loripes. It is found on the upper slopes of tropical, shallow reefs, at depths of between 5 and 25 m (16 and 82 ft), and reaches maturity at over eight years.
