范马南陨石坑(Van Maanen)是月球背面北半部一座古老的大撞击坑,约形成于45.5-39.2亿年前的前酒海纪[1],其名称取自荷裔美籍天文学家阿德里安·范马南(Adriaan Van Maanen,1884年-1946年),1970年被国际天文学联合会批准接受。

该陨坑西侧毗邻基丁努环形山、西北靠近特斯拉陨石坑、更大的贝克勒尔环形山则位于它的北面[2]

该陨坑中心月面坐标36°02′N 128°11′E / 36.03°N 128.18°E / 36.03; 128.18,直径46.42公里[3],深度约2.29公里[1]

范马南陨石坑自形成来,已被后续的撞击严重损毁,现已成为月表上一处带有一圈嶙峋边缘的洼地,其坑壁也已严重磨损且边沿难辨,环四周覆盖了一些更小的、已磨损钝化的小陨坑。该陨坑侧壁较周边地形最大高出1210米[1],内部容积约有3000公里3[1]。坑底表面崎岖不平,显示散布有许多小撞击坑。

按惯例,最靠近范马南陨石坑的卫星坑将在月图上以字母标注在该坑的中心点旁。
