Eddisbury hill fort, also known as Castle Ditch, is an Iron Age hill fort near Delamere, Cheshire, in northern England. Hill forts are fortified hill-top settlements constructed across Britain during the Iron Age. Eddisbury is the largest and most complex of the seven hill forts in the county of Cheshire. It was constructed before 200–100 BC and expanded in 1–50 AD. In the 1st century AD, the Romans slighted the site. It was reoccupied in the 6th–8th centuries AD, and an Anglo-Saxon burh was probably established at Eddisbury in 914. In the medieval and post-medieval periods quarrying and farming have damaged the site. Ownership is currently split between the Forestry Commission and a local farm. Eddisbury is protected as a Scheduled Ancient Monument.

Hill forts developed in the Late Bronze and Early Iron Age, roughly the start of the first millennium BC. The reason for their emergence in Britain, and their purpose, has been a subject of debate. It has been argued that they could have been military sites constructed in response to invasion from continental Europe, sites built by invaders, or a military reaction to social tensions caused by an increasing population and consequent pressure on agriculture. The dominant view since the 1960s has been that the increasing use of iron led to social changes in Britain. Deposits of iron ore were located in different places to the tin and copper ore necessary to make bronze, and as a result trading patterns shifted and the old elites lost their economic and social status. Power passed into the hands of a new group of people. Archaeologist Barry Cunliffe believes that population increase still played a role and has stated "[the forts] provided defensive possibilities for the community at those times when the stress [of an increasing population] burst out into open warfare. But I wouldn't see them as having been built because there was a state of war. They would be functional as defensive strongholds when there were tensions and undoubtedly some of them were attacked and destroyed, but this was not the only, or even the most significant, factor in their construction".
