Hofsta, Manor house in Björkvik parish, Katrineholm Municipality, Sweden

Hofsta is a manor house standing on the northwestern shore of Lake Yngaren with architectural elements from different construction periods spanning several centuries. The west wing's ground floor dates from the 15th century while the main building received its present design in 1746.

The manor developed over several centuries beginning with the west wing in the 15th century before undergoing major redesign in the 18th century. The 1746 remodeling shaped its present appearance and established the main building's current form.

The estate's name lives on in the families who held it: Ulfsparre, von Berchner, von Meijerhelm, Ribbing, Oxenstierna and Mörner followed one another after Johan Berndes, who united Hofsta into a single property in the mid-17th century. Since 1912 it has belonged to members of the von Arnold family.

Hofsta lies in Björkvik parish, Katrineholm Municipality, on the shore of Lake Yngaren; the sources disagree on whether this is the northwestern or the southern shore. The estate is private, held by the von Arnold family since 1912, so the buildings are seen from outside rather than toured.

In David Fincher's 2011 film The Girl with the Dragon Tattoo, Hofsta's main building appears as the Vanger estate where Henrik Vanger lives. The production adapted Stieg Larsson's novel Män som hatar kvinnor.
