Dreghorn is a village in North Ayrshire, Scotland, 3.5 kilometres east of Irvine town centre, on the old main road from Irvine to Kilmarnock. It is sited on a ridge between two rivers. As archaeological excavations near the village centre have found a significant neolithic settlement provisionally dated to around 3500 BC, as well as medieval structures, scholars have suggested that Dreghorn could be Britain's oldest continuously inhabited village.
