Locking Castle was a castle that once stood on Carberry Hill near the site of RAF Locking in Locking in the North Somerset district of Somerset, England. It has been scheduled as an ancient monument.{{NHLE|desc=Locking Castle|num=1008301|accessdate=23 July 2011}}{{NHLE|desc=Motte and bailey castle and associated earthworks south of Locking Head Farm|num=1008301|accessdate=30 September 2016}}
It was a motte and bailey on Carberry Hill. Excavations in 1902 identified the remains of a small stone chamber surrounded by a ditch.{{cite web|title=Locking Castle|url=http://archaeologydataservice.ac.uk/archsearch/record.jsf?titleId=1014156|publisher=Archaeology Data Service|accessdate=30 September 2016}} Fragments of pottery and the remains of a sword were also found.{{PastScape|mname=Locking Castle|mnumber=192672|accessdate=22 July 2011}} A coin from the period of Edward IV was also uncovered.
Around the site of the castle is a {{convert|60|m}} long bank which is around {{convert|1.5|m}} high and a ditch.{{cite web|title=Locking Castle, Carberry Hill|url=http://castlefacts.info/Castledetails/Castledetails3?Uin=12019|publisher=Castlefacts|accessdate=30 September 2016}} An area west of the inner bailey has been identified as a possible pillow mound.
The origin of the castle is unclear. It may have been part of the manor of Kewstoke or alternatively Hutton. The two manors were combined and given by Henry I to Geoffrey de Dun. In 1214 Locking was given to Woodspring Priory and would have ceased to have military significance.{{cite book|last=Dunning|first=Robert|title=Somerset Castles|year=1995|publisher=Somerset Books|location=Tiverton|isbn=978-0-86183-278-1|pages=39–40}}
