Gelli Diogyn Hillfort is a prehistoric defensive earthwork located in Carmarthenshire, Wales, designated as a Scheduled Ancient Monument under the reference CM293. The site comprises an univallate hillfort, meaning it is defended by a single rampart and ditch, characteristic of Iron Age fortifications in Wales dating from the first millennium BCE. The earthwork occupies a commanding position that would have provided strategic advantage for settlement and defence during the late prehistoric period. The monument survives as a substantial earthwork feature within the landscape, retaining archaeological and historical value as evidence of Iron Age settlement patterns and fortification practices in southwest Wales.
