Bamboo coral, family Keratoisididae (formerly included in Isididae as the subfamily Keratoisidinae) is a family of coral of the phylum Cnidaria. It is a commonly recognized inhabitant of the deep sea, due to the clearly articulated skeletons of the species.

Prior to 2021, bamboo corals was the vernacular name of the family Isididae, the definition of which was completely different from its current definition (see Isididae for details). This former family Isididae was accepted prior to 2021 because its members had their articulated skeletons with proteinaceous joints, but the family was shown to be paraphyletic after it was found that this had evolved at least five separate times.

As of 2023, the taxonomy of Keratoisididae is being actively revised.
