Højriis Castle is a manor house located at Sallingsund, 7 km south of Nykøbing, on the island of Mors in the north-west of Denmark.

The first known owner is Johan Skarpenberg, a knight in the service of Queen Margrethe I, who owned several other estates in the area, including Spøttrup Castle in Salling on the other side of the water.

In the 20th century Højriis was hit hard by the adverse times for Danish manors.

The castle is a three-winged complex built in the Historicist style which dominated Danish architecture at the time of its construction.

The north-west wing and the tower were designed by Hans Jørgen Holm and built in 1859.
