Coralliidae, also known as precious corals, is a taxonomic family of soft corals belonging to the order Scleralcyonacea of the phylum Cnidaria. These sessile corals are one of the most dominant members of hard-bottomed benthic environments such as seamounts, canyons and continental shelves. From this coral family results 69 descendants in which each species plays a key role in forming habitats for a variety of marine species.

Due to their unique trait of possessing a red calcium carbonate skeleton, these corals can be harvested in order to create handcrafted amulets, jewelry and other valuable artifacts, giving rise to its reputed name of "precious corals". Correspondingly, members of this family are vulnerable to the negative impacts of overharvestation imposed by mass coral trade.
