Hörningsholm Castle (Swedish: Hörningsholms slott) is a castle in Sweden. It is located on a cliff by an inlet of the Baltic Sea some kilometres from Södertälje. The castle was most probably built by the Sture family during the late 15th and early 16th century, was burnt to the ground by Russian troops in 1719 and rebuilt in its present shape by architect Carl Hårleman. It was renovated in 1919-20 by architect Ivar Tengbom.

The foundations of the presently visible building, including the basements, date from a castle that was erected on the cliff most probably at the end of the 15th century, when the land was owned by Nils Bosson Sture. The history of the estate, however, goes even further back, although earlier there was no fortification on the site.

The preceding farmstead was by 1260 in the possession of a landowner called Karl Ulfsson, who joined the Teutonic Order in a crusade against non-Christians in the present-day Baltic states. He died in the Battle of Durbe and in his will left several of his farms to the Teutonic Order. It is therefore possible but not certain that the land for a while was in the possession of the crusader order. Little is known of the fate of the farmstead until the 15th century, when it is known to have been in possession of one Erengisle Nilsson (died 1469); his widow sold the land to Nils Bosson Sture who most probably began construction of the castle.

It stayed in the Sture family until 1616. The family built and expanded the castle into a late Medieval–Renaissance castle. In 1520, it was occupied by a garrison of 70 Danish troops who pillaged the castle, but they were driven out by troops loyal to Gustav Vasa during the Swedish War of Liberation. After 1616 the castle had several different owners, among them Johan Oxenstierna.
