Merulinidae is a family of reef-building stony corals.

All the genera in this family are colonial, reef-building corals.

Skeletal structures are similar to those of Faviidae but are highly fused, without paliform lobes.

The valleys are superficial or may be indistinct because of fan-like spreading or contortions in the ridges.
