Mugdock Castle was the stronghold of the Clan Graham from the middle of the 13th century. Its ruins are located in Mugdock Country Park, just west of the village of Mugdock in the parish of Strathblane. The castle is within the registration county of Stirlingshire, although it is only 2 kilometres (1.2 mi) north of Milngavie, East Dunbartonshire, on the northern outskirts of Greater Glasgow.
