Liljeholmsbadet, Swimming pool building in Södermalm, Stockholm, Sweden.

Liljeholmsbadet is a floating bathhouse located in Liljeholmsviken near Hornstulls strand in Stockholm. The structure contained a swimming pool with varying water depths suited for different swimming abilities.

Designed by architect Gunnar Leche, the bathhouse was built in 1930 at the Brandholmen shipyard in Nyköping and towed to Stockholm via the Södertälje canal. In the 1950s it sank, was salvaged, renovated and moved about 100 metres west. A major renovation followed in 2001 with volunteer work by Liljeholmsbadets vänner.

The name combines Liljeholm with badet, "the bath". The pool water was kept at about 30 degrees, and in 2001 volunteers from the association Liljeholmsbadets vänner carried out part of the renovation work themselves. The building is green-marked by the Stockholm City Museum, a rating for buildings of high cultural-historical value.

The building is visible from the waterfront and stands out due to its condition and floating structure. Visitors should know that the facility is not currently operational and can only be viewed from the shore.

The original hull was judged unusable after underwater surveys, so a new pontoon is being built while the old one was given to a private owner in Grisslehamn. The bathhouse itself was towed away from Hornstulls strand on 30 October 2025, passing Skanstull and Danvikstull to a shipyard in the archipelago.
