Cuxhaven radar tower, Maritime radar tower in Cuxhaven, Germany.

The Cuxhaven radar tower is a seven-storey, 34-metre-high tower of the federal Waterways and Shipping Office, built in 1960 and standing on 64 wooden piles beside the Elbe fairway at Bei der Alten Liebe/Axel-Bundsen-Ufer. It is a listed building and part of the land radar chain in the Elbe estuary.

The Cuxhaven radar tower was built in 1960 on 64 wooden piles in the Elbe fairway and inaugurated by federal transport minister Hans-Christoph Seebohm. It belongs to the chain of land-based radar stations in the Elbe estuary, which replaced conventional navigation marks from the 1950s. The ship reporting service occupied the top floor until 1996, and the tidal direction indicator was decommissioned the same year.

The tower's name changed with its use: long called Radarturm, it is now also known as Hafenkontrollturm, the harbour control tower. Since 1996 the tide direction indicator has been out of service, and in 2019 the webcam on the tower was switched off and moved to Steubenhöft. The building also houses the Havariekommando, the joint federal and coastal-state emergency command at Am Alten Hafen 2.

The tower stands at Bei der Alten Liebe/Axel-Bundsen-Ufer on the Elbe fairway, a short walk from the Alte Liebe waterfront in Cuxhaven. It is a working building of the Waterways and Shipping Office and the Havariekommando, not a visitor attraction, so there is no lift or viewing platform; the structure is seen from the outside.

The tower stands on 64 wooden piles driven into the Elbe fairway, and its top floor housed the ship reporting service until 1996. The tide direction indicator was switched off that same year, and the webcam on the tower went offline in 2019, moving to Steubenhöft. Since 2020 the building has also housed the Havariekommando, the joint federal and coastal-state emergency command.
