The Coriobacteriia are a class of Gram-positive bacteria within the Actinobacteria phylum. Species within this group are nonsporulating, strict or facultative anaerobes that are capable of thriving in a diverse set of ecological niches.Gordonibacter species are the only members capable of motility by means of flagella within the class. Several species within the Coriobacteriia class have been implicated with human diseases that range in severity. Atopobium, Olsenella, and Cryptobacterium species have responsible for human oral infections including periodontitis, halitosis, and other endodontic infections.Eggerthella species have been associated with severe blood bacteraemia and ulcerative colitis.

The Coriobacteriia class currently consists of 16 genera within two orders and three families. The Coriobacteriales order consists of two families, the Coriobacteriaceae and Atopobiaceae. The Coriobacteriaceae family contains the Collinsella, Coriobacterium, Enorma, Parvibacter, and Senegalimassilia genera, while the Atopobiaceae contain Atopobium and Olsenella. The Eggerthellaceae consist of a single family (Eggerthellaceae) and the remaining Coriobacteriia genera (Adlercreutzia , Asaccharobacter, Cryptobacterium, Denitrobacterium, Eggerthella, Enterorhabdus, Gordonibacter, Paraeggerthella, and Slackia).
