Radok Lake is a meltwater lake in Antarctica, three miles (4.8 km) southwest of Beaver Lake and 15 miles (24 km) southeast of the Aramis Range, Prince Charles Mountains. It is about four miles (6.4 km) long and marked by a slender glacier tongue feeding into it from the west. It was plotted by Australian National Antarctic Research Expeditions (ANARE) from air photos taken by the RAAF Antarctic Flight in 1956. The lake was named for Uwe Radok, Reader (head) of Meteorology Department at the University of Melbourne, who greatly assisted Australian National Antarctic Research Expeditions (ANARE)'s glaciological program.
