Crookston Castle is a ruined medieval castle located in the Pollok (Scottish Gaelic: Pollag) area and about 5 miles southwest of the city of Glasgow, Scotland (Scottish Gaelic: Glaschu, Alba). The present castle, built by the Stewarts of Darnley around 1400, is built on the site of a previous 12th century timber and earth castle constructed by Sir Robert de Croc. A defensive ring-ditch from this earlier fortress surrounds the remaining structure. The castle was once in the possession of the Earls and Dukes of Lennox. Following previous damage sustained by bombardment in 1489 and a siege in 1544 the castle underwent significant repairs.
At the site are the remains of a three stone tower house built upon a hill. The ruins of one of the four taller square towers that once framed it can still be seen. Sir John Stirling-Maxwell presented the Castle to the National Trust for Scotland in 1931 as its first property.
