Trångsunds herrgård, Manor house in Huddinge Municipality, Sweden

Trångsunds herrgård is a manor house on the western shore of Lake Drevviken in Huddinge Municipality. Its main building, designed by Carl Fredrik Adelcrantz, is a two-storey cubic house with a säteri roof in early Gustavian style, built in half-timbered technique. The interior is also Gustavian, and the building has thirteen rooms. Two wings stand west of the courtyard, with further wings on the lake side to the east.

Carl Fredrik Adelcrantz acquired the estate in 1762 and designed the manor house, which then became a gathering place for artists and writers. This period established the property as a cultural destination in the region.

The name Trångsund comes from the narrow strait (det trängsta) in nearby Drevviken. Tradition calls the estate "Drevvikens pärla", the Pearl of Drevviken. Adelcrantz kept a "court" of nine unmarried female relatives aged 30–80 at the manor, since all widows and unmarried women were then under male guardianship.

The manor stands on the western shore of Lake Drevviken in Huddinge Municipality, within Stockholm County, not in Stockholm city. It is a private residence, so visits are limited to the view from surrounding paths and roads. The grounds include wings, a former orangery and a garden.

The Dinkelspiel family has owned the property since 1936 and continues to use it as a private residence. This long uninterrupted ownership makes the site an example of enduring family stewardship.
