Aeolidioidea, also known as aeolid nudibranchs, is a superfamily of nudibranchs. They are marine gastropod molluscs in the suborder Aeolidacea.^[1]^[2]

Taxonomy

Gosliner et al. (2007) elevated the subfamily Babakininae, which was within Facelinidae, to the family level, as Babakinidae.^[3] A study of facelinid relationships in 2019 removed several facelinid genera to the family Myrrhinidae.^[4]

According to Korshunova and colleagues (2025), the following families are recognised in the superfamily Aeolidiidae:^[2]

Family Aeolidiidae Gray, 1827
Family Babakinidae Roller 1973
Family Facelinidae Bergh, 1899
Family Favorinidae Bergh, 1899
Family Glaucidae Gray, 1827
Family Myrrhinidae Bergh, 1905
Family Pleurolidiidae Burn, 1966
