The Namsos Line (Norwegian: Namsosbanen) is a 51-kilometer-long (32 mi) railway line between the village of Medjå and the town of Namsos in Trøndelag county, Norway. The line branches off from the Nordland Line at Grong Station and runs through the municipalities of Grong, Overhalla, and Namsos. The line largely follows the river of Namsen (and it crosses the river twice). The section from Grong to Skogmo is maintained, although not used for ordinary traffic. The section from Skogmo to Namsos is closed, but the infrastructure remains.
