Favia is a genus of reef building stony corals widespread throughout the Atlantic and Indo-Pacific Oceans. Members of this genus are massive and form colonies. They are dome-shaped or flat, and some may be leafy, almost like foliage of a tree.

There is much diversity in form even among individuals of the same species. Corallites project slightly above the surface of the coral and each has its own wall. Septae and costae linked to the corallite are well developed and covered by fine teeth. The polyps extend and feed during the night only. The columella (small column-like structure) is wall-like and spongy.

The World Register of Marine Species includes 27 species in the Favia genus. The type species, (F. favus), was first published in 1775, based on a description by discoverer Peter Forskal, who died of malaria in 1763 at the age of 31.
