or is a river in the municipality of Rana in Nordland county, Norway. The river flows out of the eastern part of the lake Virvatnet. The stream Boneselva meets Virvasselva about east of the lake Virvatnet. This is a large, continuous, very rich and untouched wetland area with tarns, rivers, marshes, and very tight vegetation. Virvasselva has a good population of Arctic char.
After about, the river Virvasselva reaches a pumping station where most of the water is diverted through a tunnel to flow west to supply the Rana power station. The much smaller river then continues north and meets the main river Ranelva at Elvmøtheia in the Dunderland Valley.[1]
