Häringe Castle, Manor castle in Södermanland, Sweden

Häringe Castle is a two-storey manor with a copper-clad säteritak roof, given its current Karolinian appearance in the 1770s under Fabian Löwen. The south-west wing, now called the Lake Wing, belonged to the earlier building and served as temporary housing during construction in 1651–1657. The interior holds five dining rooms and six salons, with 98 hunting trophies and Gustav II Adolf's field trumpet displayed in the entrance.

Gustaf Horn had the present main building erected between 1651 and 1657, and he died the year it was finished. The southwest wing, later called the Sjöflygeln, served as temporary housing during the works and belonged to the earlier house on the site. In 1681 the Crown reclaimed the estate at the reduction, but Agneta Horn's son Gustaf Cruus recovered it after legal proceedings. Fabian Löwen bought it in 1769 and made it a fideicommissum for his family.

Under Axel and Marguerite Wenner-Gren in the 1930s–1960s, Häringe hosted guests such as Greta Garbo, Joséphine Baker, Danny Kaye, Karl Gerhard and Zarah Leander. The couple are buried beneath a memorial stone near the front eastern wing. Since 2023 the TV programme Förrädarna has been recorded at the castle.

The manor lies approximately 35 kilometers south of Stockholm and is easily accessible from the city. The property currently operates as a private hotel and venue, so visitor access may be limited to guests and event participants.

The property features underground tunnels and a bowling alley from earlier renovations that still exist today. It was also the location of Sweden's first outdoor swimming pool equipped with a slide.
