肺螺類（學名：Pulmonata），亦作有肺類，舊作有肺目、肺螺目或肺螺亞綱，是腹足綱異鰓類支序之下的一個非正式群組。這個群組包括有螺和蛞蝓，均可以透過其外套膜肺（pallial lung）而不是鰓來呼吸空氣。本群組除了包括有蝸牛和淡水螺，還包括多個海螺的科。

傳統定義的肺螺類分類單元的物種在Jörger et al. (2010)被發現原來是個多系群^[1]。肺螺類已知從石炭紀開始就已經開始出現，直到現在^[2]。

肺螺類物種有一個心室和一個腎臟，還有一個相互連接、左右對稱的神經系統。外套膜腔位於身體的右側，而且沒有鰓，而是演變成一個佈滿血管的肺。大多數物種都有殼，但沒有口蓋，而且本分類元還包括有幾種沒有外殼的蛞蝓。肺類類物種都雌雄間性，部份群組還擁有用作交配的戀矢（love darts）^[3]

2010年分類

Jörger et al. (2010)^[1] analyzed major groups within the Heterobranchia using genetic data and found that Pulmonata as traditionally defined was polyphyletic, for instance some pulmonates were more closely related to Sacoglossa and Acochlidia. They proposed the more inclusive taxon Panpulmonata to unite the clades Siphonarioidea, Sacoglossa, Glacidorboidea, Pyramidelloidea, Amphiboloidea, Hygrophila, Acochlidia and Eupulmonata.^[1]
