The Battle of Auldearn was an engagement of the Wars of the Three Kingdoms. It took place on 9 May 1645, in and around the village of Auldearn in Nairnshire. It resulted in a victory for the royalists, led by the Marquess of Montrose and Alasdair MacColla, over Sir John Urry and an army raised by the Covenanter-dominated Scottish government. The pibroch Blár Allt Earrann commemorates the battle. The battlefield has been included in the Inventory of Historic Battlefields in Scotland and is protected by Historic Scotland under the Historic Environment (Amendment) Act 2011.
