The Kragerø Line (Norwegian: Kragerøbanen) was a 27-kilometer (17 mi) long railway line between Neslandsvatn and Kragerø in Telemark, Norway. It was opened on 2 December 1927 as part of the Sørlandet Line. From 10 November 1935, the Sørlandet Line was extended from Neslandsvatn to Arendal, and the Kragerø Line became a branch. It was mostly served with feeder trains, although a though train to Oslo was kept until the 1970s.
