Berriasellinae is a subfamily of very late Jurassic and very early Cretaceous perisphinctoid ammonites in the family Neocomitidae. Berriasellinae comprises generally compressed, evolute genera, typically with furcated ribbing, and in some a smooth ventral band or groove. Berriasellinae are derived from the Ataxioceratidae and gave rise to the other Neocomitidae. The short lived Himalayitidae from the uppermost Jurassic have a similar appearance but differ in being generally broader and having sharper ribbing.

In current classifications (e.g. Donovan et al. 1981) berriasellid perisphinctaceans are included in the Neocomitidae as a subfamily, the Berriasellinae. In older classification such as the Treatise on Invertebrate Paleontology, part L (1957), neocomitid genera are included in the Berriasellidae, sensu lato, as the Neocomitinae.

Berriasellinae includes the genera Andiceras, Berriasella, Blanfordiceras, Delphinella, Elenaella, Jabronella, Parandiceras, Raimondiceras, Subalpinites, Substeueroceras, and Tirnovella.
