The Namsos Line (Norwegian: Namsosbanen) is a 51-kilometer (32 mi) long railway line between Medjå and Namsos in Nord-Trøndelag, Norway. The line branched off from the Nordland Line at Grong Station and runs through the municipalities of Grong, Overhalla and Namsos, largely following, and twice crossing, the river of Namsen. The section from Grong to Skogmo is maintained, although not used for ordinary traffic.
