耳螺科（学名：），亦作耳蝸牛科，是腹足綱耳螺總科（学名：）之下的一個科。耳螺科物種體型細小，皆可呼吸空氣。舊屬原始有肺目或基眼目的松螺總科，之後耳螺科改屬耳螺總科。2005年《布歇特和洛克羅伊的腹足類分類》，整個耳螺總科仍被歸到基眼類非正式群組。在2017年《布歇特等人的腹足類分類》，耳螺科聯同另外兩個科共同組成耳螺目。

型態描述
本科物種螺殻的一大特徵，除了其耳狀的螺殻外，還有其鋸齒狀的殻口。

分佈及棲息地
本科物種遍佈全世界，但仍主要集中於印度洋-西太平洋海域。部分物種嗜鹽，常栖息在河口半淡鹹水域或紅樹林的高潮區、鹽沼地等範圍。儘管本科物種可呼吸空氣，而事實上在熱帶亦有部分物種可完全營陸生，但其餘物種仍不時要返回海水裡，所以WoRMS指本科物種的棲息環境同時包括海洋、鹹淡水交界及陸生。
