TT-Line

TT-Line GmbH is a shipping company based in Lübeck, Germany, which has been providing ferry service between Travemünde in Schleswig-Holstein and Trelleborg in southern Sweden since 1962. Since 1992, it has also operated a service from Rostock to Trelleborg (until 1997 marketed as TR-Line) and from Swinoujscie in Poland. As of 2023, TT-Line owns nine ferries.

The company is ultimately owned by the German business profiles Bernard Termühlen and Arend Oetker through the holding company Trampschiffahrt GmbH & Co. KG.
