Mneme Lake (Bulgarian: езеро Мнема, romanized: ezero Mnema, IPA: [ˈɛzɛro ˈmnɛmɐ]) is the oval-shaped 220 m long in southwest–northeast direction and 85 m wide lake on the northwest coast of Livingston Island in the South Shetland Islands, Antarctica. It has a surface area of 1.3 ha and is separated from the waters of Barclay Bay by a 12 to 40 m wide strip of land. The lake and its vicinity lie in a restricted zone of scientific importance to Antarctic microbiology, part of the Antarctic Specially Protected Area Byers Peninsula.

The feature is named after Mneme, the nymph of memory in Greek mythology.

Mneme Lake is situated on Ivanov Beach just west of Rowe Point and centred at 62°35′40.7″S 60°54′30″W / 62.594639°S 60.90833°W / -62.594639; -60.90833, which is 2.5 km northeast of Bilyar Point. Bulgarian mapping of the area in 2009 and 2017.
