Dalzell House is a historic house in Motherwell, North Lanarkshire, Scotland. It is located to the south of the town, on the north bank of the River Clyde. At its core is a 15th-century tower house, with extensive additions built during the 17th and 19th centuries. In the 1980s the house was restored and divided for sale as eighteen private apartments, while the surrounding Dalzell estate is now owned by North Lanarkshire Council. The house is protected as a Category A listed building, and the grounds are listed on the Inventory of Gardens and Designed Landscapes in Scotland.
