Drumanagh is a large coastal promontory fort on a 17-hectare headland north of Loughshinny, County Dublin, defended on the landward side by three parallel banks and ditches. While the earthworks are of Iron Age character, the site has produced a substantial assemblage of Roman and Romano-British material dating principally from the 1st to 2nd centuries AD, suggesting sustained contact with the Roman world during a period when Ireland lay outside the Empire.

Drumanagh is the most significant Roman-period site in Ireland and has been interpreted variously as a native trading emporium, a beachhead for Roman or Romano-British traders, or — more controversially, in a 1996 Sunday Times claim — a possible Roman military bridgehead. Most scholars now favour an interpretation as a major contact port linking Hiberno-Roman trade with the province of Britannia, possibly tied to the brief Agricolan interest in Ireland recorded by Tacitus.
The site has never been systematically excavated; most finds derive from unauthorised metal-detecting in the 1970s–80s and are held by the National Museum of Ireland, including Roman coins (Titus, Trajan, Hadrian), brooches, ingots, and fragments of Roman copper-alloy vessels. Geophysical survey and limited recent fieldwork have indicated internal occupation features, but the full character of activity within the enclosure remains poorly
