Eskilstuna House (Swedish: Eskilstunahus) was a royal palace in Eskilstuna, in present day Södermanland County, Sweden. It was erected on the site of a medieval monastery in the 16th century, and was later destroyed in a fire in 1680. The palace was the county seat of Eskilstunahus County during its existence, before its merger into Södermanland County in 1683.
The palace and its gardens were located on the site where the first church in the area had been erected by Saint Eskil. In the late 12th century or early 13th century a monastery belonging to the Hospitallers had been established here, which later was confiscated during the Swedish Reformation in 1527. King Gustav I had the monastery rebuilt into a royal palace. He and his sons occasionally used Eskilstuna House as a royal residence. Duke John's daughter Anna was born in the palace during his stay here in May 1568, and in June the same year the rebellion of the dukes John and Charles against their royal brother King Eric XIV was launched from the palace, leading to the imprisonment of Eric and the ascension of Duke John to the throne as John III. In 1589 Mary of the Palatinate, the first wife of Duke Charles (later King Charles IX) died in Eskilstuna House.
