Panpulmonata is a taxonomic clade of snails and slugs in the clade Heterobranchia within the clade Euthyneura.[1]

Panpulmonata was established as a new taxon by Jörger et al. in October 2010.[1]

The older name "Pulmonata" referred to a group of euthyneuran gastropods which were considered to be "air-breathers". In contrast, "Opistobranchia" grouped various, mostly marine euthyneuran lineages, often with reduced shell. Phylogenetic analyses have shown that none of these two groups was monophyletic.[2] The former "Pulmonata" should also include several groups that lack an air-filled lung (Acochlidiacea, Sacoglossa and Pyramidelloidea). The name "Pulmonata" also inaccurate when applied to some of the more traditional pulmonate taxa such as Siphonarioidea or Hygrophila, most members of which lack permanently air-filled lungs as well.[1] To emphasize the complete change in taxonomic concepts following from the molecular phylogenetic analyses but keep some continuity in the naming, Jörger et al. (2010) renamed the expanded "Pulmonata" as Panpulmonata

The clade consists of following taxa:[1][3]
