Abyssochrysoidea is a superfamily of deep-water sea snails, marine gastropod mollusks unassigned in the order Caenogastropoda.

[1] 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)[2] and then Abyssochrysidae was also moved to Abyssochrysoidea.
