The Pectinoidea are a superfamily of marine bivalve molluscs, including the scallops and spiny oysters.^[1]

All members of this superfamily have a triangular resilium with a nonmineralized medial core that functions below the hinge line.^[2]

According to the World Register of Marine Species, the Pectinoidea include these families (all taxa marked † are extinct):

• Cyclochlamydidae
• Entoliidae
• Neitheidae †
• Pectinidae (scallops)
• Pleuronectitidae †
• Propeamussiidae some are known as glass scallops
• Spondylidae thorny oysters
• Tosapectinidae †

• Propeamussidae: synonym of Propeamussiidae
• Syncyclonematidae: synonym of Entoliidae
