Königlicher Gutshof Sköldnora, Royal estate in Upplands Väsby Municipality, Sweden

Sköldnora Manor is a grand estate located on the eastern shore of Lake Norrviken, featuring a central risalit and an exposed basement section. The main building is accompanied by two outbuildings that together form a cohesive complex.

Sköldnora is first mentioned in 1276. In 1296 Birger Persson, father of Saint Birgitta, acquired it from canon Rörik Matsson of Sollentuna, exchanging Finsta for Skällnora. At his death in 1327 it passed to his son-in-law Ulf Gudmarsson, Birgitta's husband. In the 14th century it was given to Vadstena Abbey, and Gustav Vasa confiscated it to the crown; between 1552 and 1560 it was his private avelsgård.

The estate's name survives in Carl Jonas Love Almquist's 1838 novella Skällnora Qvarn, set at a mill near the manor and counted among Sweden's first crime stories. The present main building, finished in 1741, has interior work attributed to Johan Pasch and Charles Cousin.

The main building and two outbuildings are listed as Byggnadsminne; the main house was designated in 1982. The estate is private property, so visitors view the exterior only. The front facade shows one visible storey with a central risalit, while the rear reveals the full lower storey.

The nearby mill building inspired one of Sweden's earliest crime stories, written by Carl Jonas Love Almquist. This literary connection links the estate to an important work in Scandinavian literary history.
