Södervärnstornet is a building in Malmö, Sweden originally built in 1916 to serve as a water tower.

The tower is located in the Möllevången neighbourhood where Nobelvägen and Spårvagnsgatan intersect.

[1][2] Many residents of Malmö use the nickname Kuken, 'The Cock', for the tower, owing to its perceived phallic shape.

[2][1] On 1 July 2018, both Södervärnstornet and the Pildammarna water tower were acquired by Malmö Municipality for a symbolic sum of 1 krona.

[4] These plans were put on hold in July 2023, with the city wishing to give the local community the task of finding a new, public use for the tower.
