Nettilling Lake () is a cold freshwater lake located toward the south end of Baffin Island in the Qikiqtaaluk Region, Nunavut, Canada. It is 30th largest lake in the world by area, and the world's largest lake on an island, with an area of 5,542 km2 and a maximum length of 123 km. The lake is in the Great Plain of the Koukdjuak about 280 km northwest of Iqaluit. The Arctic Circle crosses the lake. The lake's name is of Inuktitut origin, coming from the word for the adult ringed seal. Franz Boas explored its southern shore in 1884.
Nettilling is the largest lake in Nunavut. It is fed by the second largest lake on Baffin Island, Amadjuak Lake; as well as several other smaller lakes and streams. It empties west via the very shallow Koukdjuak River into Foxe Basin.
