Acton (also known as North Action) is a hamlet in Northumberland, located about 1½ miles north of the village of Felton, and a short distance west of the hamlet of Old Felton. The settlement of Acton includes Action Hall, Action House and a number of cottages. Acton Dean, the valley of Mere Burn (a tributary of the River Coquet), is to the north of Action. The separate farmstead of South Action is located by Action Burn (also a tributary of the Coquet), about ¾ mile south of North Action. At North Action are the earthwork remains of the medieval village of Action, which had been recorded as part of the Barony of Mitford in the 13th century. In the 19th century, Acton with Old Felton was a township in the ancient Parish of Felton.
