Numedalslågen is a river located in southeastern Norway. It stretches for over 250 kilometres through the counties of Vestfold and Buskerud, beginning at the Hardangervidda plateau and meeting the ocean at Larvik in Vestfold. Numedalslågen is one of Norway's longest rivers. There are a number of hydroelectric plants located in the higher range of Numedalslågen.
Numedalslågen is known for being a good location for salmon fishing, although a parasite known as Gyrodactylus salaris has recently been found in Numedalslågen that may pose a threat to its salmon stock. Among the other fish species of Numedalslågen are trout, eel, and pike.
