里利克特湖是南极洲的湖泊，位于南设得兰群岛的迪塞普逊岛，处于彭杜拉姆湾东南部，由英国南极名称咨询委员会命名，现时由南极条约体系管理。

Relict Lake (62°57′S 60°36′W / 62.950°S 60.600°W / -62.950; -60.600) is a small lake lying southeast of Pendulum Cove on Deception Island, in the South Shetland Islands. So named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1957 because when Lieutenant E.N. Kendall made his survey of Deception Island in January–March 1829, Pendulum Cove extended inland to this lake, which has since been cut off from the sea.
