Acropora robusta is a species of acroporid coral found in the Red Sea, the Gulf of Aden, the southwest and northern Indian Ocean, the central Indo-Pacific, Australia, Southeast Asia, Japan, the East China Sea and the oceanic west and central Pacific Ocean. It occurs in tropical shallow reefs, mainly along margins that are exposed to the action of strong waves, and can be found at depths from 1 to 8 metres (3 ft 3 in to 26 ft 3 in).
