Baculitidae is a family of extinct ammonoid cephalopods that lived mostly during the Late Cretaceous, and often included in the suborder Ancyloceratina.[1]

Baculitid genera are characterized by a small to minute initial coil of about two whorls followed by a long straight or slightly curved shaft. Genera are distinguished on the basis of size, general shape, particulars of the suture, and ornamentation. They can reach lengths of Шаблон:Convert or more.[1]

Baculitids are found worldwide in deposits from the upper Albian to the Maastrichtian ages.[1] Related families are the Anisoceratidae, Diplomoceratidae, Hamitidae, Nostoceratidae, and Turrilitidae; all of which along with the Baculitidae are included in the superfamily Turrilitoidea.[2]

Genera included in the family include:
