忘湖(拉丁文为"Lacus Oblivionis")是月球背面的一座小月海,位于南极-艾托肯盆地内北侧,尺寸为38×24公里。1976年国际天文学联合会批准采纳了它的命名[1][2]

忘湖“夹在”两座陨石坑之间:东北40公里的"莫霍洛维奇 R 陨坑"(Mohorovičić R)和西南35公里的"斯尼亚德茨基 Y 陨坑"(Sniadecki Y),后者也部分被月海熔岩覆盖,月湖中心月面坐标20°24′S 168°30′W / 20.4°S 168.5°W / -20.4; -168.5[1]

忘湖中部较窄,外形不规则,四周环绕着高度0.5-1.5公里的山丘[3],南侧与"斯尼亚德茨基 Y 陨坑"组成了一道条狭窄的峡谷;忘湖表面最大的地貌特征是一座直径4公里的半岛,其东侧构成了一座陨坑一半的边缘,这些是截止2015年忘湖中已命名的特征[4]

忘湖表面低于月面基准高度1.1-1.3公里,熔岩厚度估计为0.1公里[5],形成于雨海纪时期 [5]
