Acropora hyacinthus is a species of Acropora described from a specimen collected in Fiji by James Dwight Dana in 1846. It was thought to have a range that includes the Indian Ocean, the Indo-Pacific waters, southeast Asia, Japan, the East China Sea and the western Pacific Ocean, but has recently been shown to be restricted to the central pacific and the Australian east coast . It lives on shallow reefs on upper reef slopes, and is found from depths of 1–25 metres (3.3–82.0 ft). Crown-of-thorns starfish preferentially prey upon Acropora corals.
