Melampidae Stimpson, 1851

耳螺科（学名：Ellobiidae），亦作耳蜗牛科，是腹足纲耳螺总科（学名：Ellobioidea）之下的一个科。耳螺科物种体型细小，皆可呼吸空气。旧属原始有肺目或基眼目的松螺总科，之后耳螺科改属耳螺总科:6。2005年《布歇特和洛克罗伊的腹足类分类》，整个耳螺总科仍被归到基眼类非正式群组。在2017年《布歇特等人的腹足类分类》，耳螺科联同另外两个科共同组成耳螺目。

本科物种螺壳的一大特征，除了其耳状的螺壳外，还有其锯齿状的壳口。

本科物种遍布全世界，但仍主要集中于印度洋-西太平洋海域。常栖息在河口半淡咸水域或红树林的高潮区、盐沼地等范围。尽管本科物种可呼吸空气，而事实上在热带亦有部分物种可完全营陆生，但其余物种仍不时要返回海水里，所以WoRMS指本科物种的栖息环境同时包括海洋、咸淡水交界及陆生。

截至2018年8月28日 (2018-08-28)，WoRMS纪录本科包括以下各个亚科与属：
