a seaport-town of South Wales, county of Pembroke, 14 miles N. of Haverfordwest. It is called by the natives Abergeuen, from its situation at the mouth of the little river Gwaen, over which there is a good stone bridge. The town is small and ill-built, and in the older part of it the street is so ill constructed as to be extremely inconvenient for the passing of carriages. The harbour is capacious, and at all times easy of access, being unobstructed by shoals or bars, and sheltered by the bold promontories of Dinas Head and Penmaenlas. The bay extends from E. to W., about 3 miles, and from N. to S. more than a mile and a half. Its general depth is from 30 to 70 feet, and ships of the largest size may anchor in all parts of it with perfect security. The trade, however, is unimportant. About 2½ miles S. of the town a French force of 1400 men, under General Tate, landed on 22d February 1797, and next day surrendered to a few militia and volunteers not half their own number. Fishguard unites with Haverfordwest and Narberth in returning a member to parliament. Pop. (1851) 1757.
