Rowallan Castle (Scottish Gaelic: Caisteal an Rubha Àlainn) is an ancient castle located in Scotland. The castle stands on the banks of the Carmel Water, which may at one time have run much closer to the low eminence upon which the original castle stood, justifying the old name Craig of Rowallan. Elizabeth Mure (died before May 1355) was mistress and then wife of Robert, High Steward of Scotland, and Guardian of Scotland (1338–1341 and from October 1346), who later became King Robert II of Scotland. She may have been born at Rowallan.
