Rissooidea (originally named Rissoacea by Gray in 1847) is a superfamily of tiny marine snails.

Following their phylogenetic analysis of snails in the rissooidean and cingulopsoidean families in 2013, Criscione F. and Ponder W.F. determined that Rissooidea was not monophyletic, and created the superfamily Truncatelloidea, which encompasses many families previously included in the superfamily Rissooidea. Several freshwater, brackish, and semi-terrestrial families and genera within Rissooidea were brought under Truncatelloidea.
