Etal Castle is a ruined medieval fortification in the village of Etal, Northumberland, England. It was built around 1341 by Robert Manners, and comprised a residential tower, a gatehouse and a corner tower, protected by a curtain wall. The castle was involved both in local feuding and the border wars between England and Scotland. There was a battle between the rival Manners and Heron families outside the walls in 1428, and in 1513 it was briefly captured by King James IV of Scotland during his invasion of England.
