厄缶环形山[1](Eötvös)是月球背面南半球一座大型撞击坑残迹,其名称取自匈牙利物理学家厄特沃什·罗兰男爵(Eötvös Loránd,1848年-1919年),1970年被国际天文学联合会正式批准接受。

该陨坑位于环壁平原-洛希环形山的西北偏北;东北偏东靠近同样破损的鲍耶环形山;西北坐落着拉普兰环形山;西南接壤更大的儒勒·凡尔纳环形山。该陨坑的中心月面坐标35°37′S 134°26′E / 35.61°S 134.43°E / -35.61; 134.43,直径101.8公里[3],深度为2.86公里[4]

厄缶环形山仅西北侧外壁保存较为完整,其余部分已成为残损、参差的环形山脊,其中东南侧几乎已不存在,该部分区域已融入到与洛希环形山边缘相连的崎岖平原;东北和西南侧壁上各坐落着一座小陨坑。残存的坑壁高出周边地形1490米[4],内部容积10338.9立方千米[4]。坑底表面相对平坦,但显示有一些细小的撞击坑以及仅剩圆形的隆起突出在表面的幽灵陨坑-现难以辨别的撞击坑残骸。

按惯例,最靠近厄缶环形山的卫星坑在月图上以字母标注在该坑中心点的旁边。
