Lumley Castle is a 14th-century quadrangular castle at Chester-le-Street in the North of England, near to the city of Durham and a property of the Earl of Scarbrough. It is a Grade 1 listed building currently being used as a hotel.

It is named for its original creator, Sir Ralph Lumley, who converted his family manor house into a castle in 1389 after returning from wars in Scotland. However, after being implicated in a plot to overthrow Henry IV he was imprisoned and ultimately executed, forfeiting his lands to the Earl of Somerset. In 1421 the ownership of the castle reverted to Sir Ralph Lumley’s grandson, Thomas.

In 1976, management of the castle was handed over to No Ordinary Hotels (although the property is still in the possession of Lord Scarbrough), who had the castle turned into the 73-bedroomed hotel it is today. It is also a picturesque backdrop for Durham County Cricket Club’s Emirates Durham International Cricket Ground, which was first used in 1995, and often houses visiting cricket teams.
