戴尔陨石坑(Dale)是位于月球正面东部赤道区的一座小撞击坑,其名称取自英国神经学家,1936年诺贝尔生理学或医学奖得主亨利·哈利特·戴尔(1875年-1968年),1976年被国际天文学联合会正式批准接受。

该陨坑西侧毗邻布雷克陨石坑;西北靠近克斯特纳环形山凯伊士环形山位于它的东北偏北;东北偏东则是克雷伊肯陨石坑; 而埃尔默陨石坑安斯加尔环形山分列它的东南和西南。戴尔陨石坑的北面则坐落着史密斯海[1]。该陨坑的中心月面坐标9°34′S 82°56′E / 9.56°S 82.93°E / -9.56; 82.93,直径23.41公里[2], 深度约1.863公里[3]

戴尔陨石坑外观呈多边形状,外侧壁已磨损和侵蚀,西南侧横跨了一座更小的碗状撞击坑。坑壁平均高出周边地形830米[4],其中北侧坑壁较其它部分更低。陨坑内部容积约为346.65公里³[4],碗状的坑底相对平坦,除显示有一些细小的陨坑外,表面没有其它醒目的地貌结构。在该陨坑附近还分布有数座难以辨清的古老撞击坑残迹。

由于该陨坑位于月球东沿,从地球上看其外观有些变形,对它的观察主要取决于月球在轨道上的摄动
