The Orthocerataceae is a superfamily of orthocerid cephalopods that lived from the late Early Ordovician to the Early Cretaceous, but is no longer in general use. The Orthocerataceae is one of two superfamilies in the Orthocerida presented in the Treatise, the other being the Pseudorthocerataceae. With the recognition of orthocerids and pseuorthocerids as separate orders, the two superfamilies became unnecessary taxa with the Orthoceraceacea and Pseudorthocerataceae left as historical references.
