The Battle of Nesbit Moor (or Nisbet Muir) was a small but significant clash between Scottish and English forces in the borders area north of the River Tweed.

In the initial foray, some 12,000 Scottish troops crossed into Cumberland and looted areas near Carlisle.

On 22 June at Nisbet, Berwickshire, the forfeited George de Dunbar, 10th Earl of March successfully led 200 English soldiers, mainly drawn from the garrison at Berwick-upon-Tweed, against 400 Scots returning from a raid on Northumberland.

Henry IV of England was given news of the skirmish while at Harborough on 30 June, and delayed plans to suppress a Welsh rebellion so that he could deal with the large-scale Scottish invasion that was then imminently expected.

In the autumn a large army of Scots led by Archibald Douglas, 4th Earl of Douglas harassed the English countryside as far south as the River Wear, and were engaged and defeated in the battle of Humbleton Hill.
