Glomma is the longest river in Norway with over 600 kilometers. It runs through the east of the country, ending in the Oslofjord near the city of Fredrikstad. The river system Pasvikelva and Ivalo, of which a significant part runs through Finland, forms the border between Norway and Finland, and Norway and Russia, is the country's second longest. Several of Norway's rivers are important for log floating and hydropower.
* Also 520 kilometers in Sweden (Klarälven - Göta älv), making it the longest river in the Nordic countries.
**Pasvikelva, which forms the border between Norway and Russia, and Norway and Finland, is connected to the river Ivalo, which runs through Finland. Without Ivalo, it has a length of approximately 143 kilometers.
The length of the rivers may vary depending on different sources due to different ways of measuring. For instance, some sources set the full length of Glomma to 621 kilometers.
