Cawdor Castle is set amid gardens in the parish of Cawdor, approximately 10 miles (16 km) east of Inverness and 5 miles (8.0 km) southwest of Nairn in Scotland. The castle is built around a 15th-century tower house, with substantial additions in later centuries. Originally a property of the Clan Calder, it passed to the Campbells in the 16th century. It remains in Campbell ownership, and is now home to the Dowager Countess Cawdor, stepmother of Colin Campbell, 7th Earl Cawdor.
The castle is perhaps best known for its literary connection to William Shakespeare's tragedy Macbeth, in which the title character is made "Thane of Cawdor". However, the story is highly fictionalised, and the castle itself, which is never directly referred to in Macbeth, was built many years after the life of the 11th-century King Macbeth.
