草席钟螺属（学名：），是原始腹足目钟螺科的一属。

拉马克于1801年将本属从林奈的钟螺属（）中分离出来，以草席钟螺（）为模式种。

本屬的學名直譯就是「單齒螺」，而這名稱也是來自中國大陸的文獻最普遍使用的譯名。然而，「單齒螺」這個譯名有歧義：還有另一個螺的屬也可譯作「單齒螺」；但本屬的台灣譯名「草席钟螺属」並不會引起歧義，所以本條採取了這個譯名。

特征
本属通常拥有厚重的圆锥状螺旋形硬壳，壳表面光滑或有螺旋凸纹，开口外缘内面有褶皱。瓷质的短轴柱坚固、呈膨大圆柱状、近基部或多或少带锯齿状，齿与基底边缘之间有方形槽沟纹。壳洞高位开口而宽阔。

分布
从印度洋中西部、中印半岛、马来群岛至大洋洲，包括菲律宾、日本、澳洲（北领地、昆士兰州、西澳大利亚州）等都有本属的分布。
