弗雷德霍姆陨石坑(Fredholm)是位于月球正面危海西侧崎岖月地上的一座小撞击坑,其名称取自瑞典数学家埃里克·伊瓦尔·弗雷德霍姆(1866年-1927年),1976年被国际天文学联合会批准接受。

该陨坑位于北面突出的马克罗比乌斯环形山和正南普罗克洛斯陨石坑中间、东北与较大的蒂斯朗陨石坑相毗邻,陨坑西侧坐落了爱湾,东、南二面分别分布着危海睡沼[1]。该陨坑中心月面坐标18°22′N 46°33′E / 18.37°N 46.55°E / 18.37; 46.55,直径13.39公里[2],深约2.169公里[3]

弗雷德霍姆陨石坑是一座圆碗状的撞击坑,带有一个平坦的小坑底,面积不到陨坑直径的四分之一。坑壁边缘清晰完整,内侧平整舒缓,具有较高的反照率。北侧壁几乎与更小的卫星坑马克罗比乌斯 E。该陨坑侧壁最大高出周边地形500米[3],形态特征隶属于BIO 型(以该类陨石坑的典型代表—毕奥陨石坑所命名)。

在1976年被国际天文学联合会正式命名前,该陨坑曾被称作卫星坑马克罗比乌斯 D
