Runcton was in the ancient hundred of Boxgrove and listed in the Domesday Book (1086) as having 26 households (six villagers, five slaves and 15 cottagers). Resources included ploughing lands, two mills and a fishery.
Prior to 1086, the Norman lord Roger of Montgomery, Earl of Shrewsbury and Chichester, gave the manor of Runcton to the Norman abbey of Troarn: in 1260, Bruton Priory in Somerset took over all the English lands of Troarn abbey. After the dissolution of the monasteries, Thomas Bowyer bought the manor of Runcton and joined it with the manor of North Mundham.
In 1848, the hamlet of Runcton had 98 inhabitants.
