The hamlet name is Anglo Saxon in origin, and means 'Ceacca's moor'. It has been suggested though that the first part of the name could stem from the ancient word ceacce, meaning 'hill'. The hamlet was first recorded in manorial rolls in 1241 as Chakemore.
It is suggested by some that Chackmore was once a village in its own right, as anciently it had its own chapel, though this has long since disappeared.
