Fishguard (in Welsh, Abergwaun), town and seaport at the mouth of the River Gwaun in Pembrokeshire, south-western Wales. Passengers, mail, and freight are carried between here and Rosslare, Ireland, across a distance of 87 km (54 mi), the shortest sea crossing to Ireland. Fishguard was formerly a fishing centre, but today its main industries are transport and tourism. Buried at St Mary's Church is Jemima Nicholas, a local heroine who marched to meet the French invaders of 1797 and personally captured 14 of them. Population (1991) 2,903.
