Castlecraig, also known as Craig Castle and Castle Craig, is a 16th-century fortification located on the north shore of the Black Isle in northern Scotland. It is on the south coast of the Cromarty Firth, 5 kilometres (3.1 mi) north-east of Culbokie and 19 kilometres (12 mi) north of the city of Inverness. The castle is protected as a scheduled monument.

Castlecraig is a ruined tower house. The north-east wing still stands and remains roofed, although another wing to the north-west has collapsed. The tower may have been used as a residence by the post-Reformation Bishops of Ross.

The New Zealand geologic formation of Castle Craig Rock is named for its similar appearance to Castlecraig.
