Ctenobactrites is an extinct genus of cephalopods that lived from the Carboniferous to the Permian. It contains seven valid species which have been found in Europe, Asia, and North America.{{cite journal |last=Shchedukhin |first=A.Y. |date=2022 |title=The first find of Bactritoidea (Cephalopoda) in the Asselian–Sakmarian beds of the Shakhtau Reef (Bashkortostan) |journal=Paleontological Journal |volume=56 |issue=5 |pages=496–502 |doi=10.1134/S0031030122050112|bibcode=2022PalJ...56..496S }} It was originally assigned to the order Bactritida, but has been proposed to be a potential member of the order Mixosiphonata.{{cite journal |last=Mutvei |first=H. |date=2017 |title=The new order Mixosiphonata (Cephalopoda: Nautiloidea) and related taxa; estimations of habitat depth based on shell structure |journal=GFF |volume=139 |issue=3 |pages=219–232 |doi=10.1080/11035897.2017.1330278|bibcode=2017GFF...139..219M }}
