埃斯平环形山'(Espin)是月球背面北半部一座古老的大撞击坑,约形成于45.5-39.2亿年前的酒海纪[1],其名称取自英国天文学家托马斯·亨利·埃斯皮内利·康普顿·埃斯平英语T. H. E. C. Espin牧师(Thomas Henry Espinell Compton Espin,1858年-1934年),1970年被国际天文学联合会批准接受。

该陨坑就位于月球正面东北边沿后,东北偏东毗邻更大的赛弗特环形山、东南靠近略小的道奇环形山、西北偏北较远处坐落了西拉德环形山,而绵长的阿尔塔莫诺夫链坑则斜伸在它的西南侧[3]。该陨坑中心月面坐标28°09′N 109°20′E / 28.15°N 109.34°E / 28.15; 109.34,直径70.01公里[4],深度约2.76公里[1]

埃斯平环形山是一座已磨损的撞击坑,外观呈多边形状,北侧壁已严重损毁,沿北侧覆盖了数座小陨坑,南侧坑壁上也坐落了一座撞击坑。该环形山坑壁最大高出周边地形1290米[1],内部容积约有4354.08立方千米[1]。坑底北部地表较为崎岖,但南部相对更平缓。西侧坑底上覆盖有一道来自西北偏北方焦尔达诺·布鲁诺陨石坑射纹束

按惯例,最靠近埃斯平环形山的卫星坑将在月图上以字母标注在该坑的中心点旁。
