The Astrocoeniidae are a small family of stony corals. The family is distributed across the tropical and subtropical oceans worldwide.
Astrocoeniids include both hermatypic and ahermatypic (reef-building) colonial corals, both with and without symbiotic zooxanthellae. The family is made up of both branching and encrusting species which can range in size from less than 5 cm (2.0 in) to more than 30 m (98 ft) across.
The World Register of Marine Species includes these genera and species in the family:
