The Halanaerobiales are an order of bacteria placed within the class Clostridia, and encompassing two families, the and the . Originally placed within the highly polyphyletic class Clostridia, according to the NCBI and LPSN, it is now thought to lie outside the Firmicutes. Halanaerobiales are halophilic obligate anaerobes with a fermentative or homoacetogenic metabolism.^[1]
