Bisatoceratidae is a family of Late Paleozoic ammonites now included in the Thalassoceratoidea characterized by thick-discoidal to subglobular, involute shells in which lobes are simple. Some forms have spiral ornamentation.

Bisatoceratidae was originally a subfamily of the Goniatitidae as Bisatoceratinae, named by Miller and Furnish, 1957, and introduced in the Treatise on Invertebrate Paleontology, Part L, 1957. Its relation to the Thalassoceratidae is tenuous.[why?]
