Abyssochrysoidea is a superfamily of deep-water sea snails, marine gastropod mollusks unassigned to an order in the subclass Caenogastropoda.
These marine snails are part of the fauna of the hydrothermal vents and other deep-water habitats.
Families within the superfamily Abyssochryoidea include:
These two families Provaniidae and Abyssochrysidae were previously placed in the "Zygopleuroid group" (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
Subsequently Provannidae was placed in the superfamily Abyssochrysoidea by Kaim et al. (2008) and then Abyssochrysidae was also moved to Abyssochrysoidea.
