The Trave (IPA: [ˈtʁaːvə]) is a river of Schleswig-Holstein in northern Germany. It is approximately 124 kilometres long, running from its source near the village of Gießelrae in Ostholstein to Travemünde where it flows into the Baltic Sea. It passes through Bad Segeberg, Bad Oldesloe, and Lübeck, where it is linked to the Elbe-Lübeck Canal. It is navigable for sea-going vessels from the Baltic to the Lübeck ports. The road from Lübeck to Travemünde goes through Herren Tunnel, which is a toll tunnel underneath the Trave.
