Barnaby's Tower stands at the southeast corner of the city walls of Chester, Cheshire, England. It is designated by English Heritage as a Grade I listed building. The tower probably dates from the 13th century, and it was damaged in 1664–66 during the Civil War. When the city walls were converted into a raised walkway between 1702 and 1708, the tower was converted to form a feature at this corner. It has been repaired on occasions since, and in 1879–80 was altered at the expense of one of the city councillors.
