The Helcionellacea is one of two taxonomic superfamilies of extinct primitive marine molluscs within the order Bellerophontida.

Helcionellaceans are characterised by cap-shaped to bellerophontiform shells; commonly with strong rugae, (transverse plications) clearly defined on both the interior and exterior of the shell; with a septum or septa partitioning off the apex, but lacking the anal emargination that is characteristic of the Bellerophontacea.

The Helcionellacea includes two families according to the Treatise, 1960, the Helcionellidae, which is the more primitive, and the Coreospiridae, which is the more derived.

The Helconellidae (Wenz, 1938) represented by the genus Helcionella (Grabau & Shimer, 1909) more closely resembles the monoplacophoran ancestor, and is characterized by elongate cap-shaped shells.

The Procarinaridae, represented by Procarinaria from the Upper Silurian of Italy and the Czech Republic, was tentatively included in the Cyrolitidae by Knight et al., 1960, and this taxon may or may not belong instead to the Helcionellacea.
