裂螺總科（學名： Fleming, 1822，亦作裂裙螺總科或透孔螺總科），其下只有裂螺科（學名： Fleming, 1822，亦作裂裙螺科、钥孔䗩科或透孔螺科），是古腹足類支序之下的一個海洋腹足纲软体动物的科。本總科的物種因其錐狀螺殼的螺尖上有一個小孔，是海螺的一個特化體。由於整個螺殼的外形就像一條裂開了一條縫的裙襬那樣，所以被稱為裂裙螺。

根據2005年《布歇特和洛克羅伊的腹足類分類》基本上包括了各種笠螺，覆蓋了原來原始腹足目的大多數物種。

分佈
本科物種的分佈是世界性的，從冰冷的寒帶到熱帶都有其物種存在。

習性
本科物種一般居住在潮間帶下部深水區的岩面或岩底。

分類
本科的屬一般可以按四個不同的亞科來分類，分別如下：
 天蓋螺亞科 Diodorinae 
 Cosmetalepas Iredale, 1924
 天蓋螺屬 Diodora 
 Lucapina G. B. Sowerby I, 1835：分佈於西非大西洋東岸的佛德角
 Megathura Pilsbry, 1890
