The Battle of Lochmaben Fair was an engagement in Lochmaben, Scotland, on 22 July 1484 between Scottish loyalists to James III of Scotland and the rebels Alexander Stewart, Duke of Albany and James Douglas, 9th Earl of Douglas, leading cavalry from England. Both exiles from Scotland, Albany and Douglas invaded with permission but not support of Richard III of England, hoping to encourage rebellion against James. Instead, they were met with armed resistance. The loyalists took the day. Douglas was captured and Albany forced to retreat.
