Romer Lake (Danish: Romer Sø) is a land-locked freshwater fjord at the northern end of King Frederick VIII Land, near Greenland's northeastern coast. The Danish military base/weather station Nord —the only inhabited place in the area— lies 50 km (31 mi) to the northeast. The lake and its surroundings are part of the Northeast Greenland National Park zone. Romer Lake was first mapped in 1933 by Lauge Koch during aerial surveys made during the 1931–34 Three-year Expedition to East Greenland (Treårsekspeditionen). It was likely named after the American paleontologist Alfred Romer (1894–1973).
