Knob Lake (60°42′S 45°37′W / 60.700°S 45.617°W / -60.700; -45.617) is the central lake in Three Lakes Valley in northeast Signy Island, in the South Orkney Islands. The name was given to the lake by the UK Antarctic Place-Names Committee because there is a glacier-scoured rock knob forming a small island near the south end of the lake.
