Andrew Harclay, 1st Earl of Carlisle (ca. 1270 – 3 March 1323), alternatively Andreas de Harcla, was an important English military leader in the borderlands with Scotland during the reign of Edward II. Coming from a knightly family in Westmorland, he was appointed sheriff of Cumberland in 1311. He distinguished himself in the Scottish Wars, and in 1315 repulsed a siege on Carlisle Castle by Robert the Bruce. Shortly after this, he was taken captive by the Scots, and only released after a substantial ransom had been paid. His greatest achievement came in 1322, when he defeated the rebellious baron Thomas of Lancaster at the Battle of Boroughbridge on 16–17 March. For this he was created Earl of Carlisle.
