Architectibranchia is a clade of marine snails, gastropod molluscs.

It was originally established containing the superfamilies Acteonoidea, Ringiculoidea, and Diaphanoidea.

[2][3] Architectibranchia was not used in the taxonomy by Bouchet & Rocroi (2005)[2] and this taxon name has been listed as an available name.

[2] Clade Architectibranchia was reinstated by Malaquias et al. in 2009;[4] they limited the taxon to Acteonoidea and Ringiculoidea.

[5] However, some of its members were included: Acteonoidea was moved to Lower Heterobranchia.
