Clawdd-Mawr is a linear earthwork in Carmarthenshire, Wales, surviving as a substantial bank and ditch that represents an important Early Medieval territorial boundary. The monument dates to the period following the Roman withdrawal from Britain, when such linear features served to demarcate Welsh kingdoms and control movement across the landscape. The earthwork's precise dating remains uncertain, though its form and scale suggest construction during the Early Medieval period when similar defensive and administrative boundaries were constructed across Wales. The site is recorded under Cadw's Scheduled Ancient Monuments register as CM110 and continues to be studied as evidence of Early Medieval landscape organisation and political geography in south Wales.
