Hammarbyleden is an artificial waterway in Stockholm which connects Lake Mälaren with Saltsjön, the westernmost bay of the Baltic Sea. The waterway is located along the southern edge of Södermalm, one of Stockholm's many islands.
The waterway is composed mostly of interconnected natural bodies of water, which were expanded and dredged in the late-1910s and 1920s; the waterway was opened in 1929. A water lock was constructed as part of the project to account for the water level variation between Lake Mälaren and the Baltic Sea.
