Lichtensteinbrücke, Iron footbridge in Tiergarten, Germany

The Lichtensteinbrücke is the eastern walkway of a paired pedestrian bridge over the Landwehr Canal in Berlin's Tiergarten. It is an arched tubular-steel truss bridge, built in 1985/86 with 106 tonnes of steel, that links the main Berlin Zoo grounds to its extension on the canal's northeast bank. Only zoo visitors and staff may use it.

The bridge was named after Martin Hinrich Lichtenstein, the physician and first director who founded the Berlin Zoo in the 19th century. The structure was built as part of the infrastructure to develop the zoo grounds.

The bridge is named after Martin Hinrich Lichtenstein, the physician who founded the Berlin Zoo and served as its first director. Its eastern walkway is reserved for zoo visitors and staff, while the western Rosa-Luxemburg-Steg, renamed in September 2012, is open to all pedestrians in the Großer Tiergarten. Below the bridge on the southern bank stands a memorial to Rosa Luxemburg, whose body is said to have been thrown into the canal near this spot in 1919.

The Lichtensteinbrücke is open only to zoo visitors and staff, so a zoo ticket is needed to cross it. The parallel Rosa-Luxemburg-Steg, on the western side of the shared structure, is freely accessible to all walkers in the Großer Tiergarten. In the evening the south-west bank of the Landwehrkanal is closed to protect the zoo's night rest.

The bridge shares its foundation with the adjacent Rosa-Luxemburg-Steg, creating a rare dual structure spanning the canal. This arrangement allows a separation between public and private zoo access routes.
