a decayed municipal borough and market-town of England, county of Suffolk, at the confluence of the Alde and the Ore, 16 miles E. by N. of Ipswich, and 80 N.E. of London. The church is a fine old building, with a square embattled tower; and there is also here a town-hall, and the remains of an ancient Norman castle. The inhabitants support themselves chiefly by the oyster fisheries in the neighbouring rivers. On account of the sea having receded from the land, the harbour of Orford has been destroyed; and this has led to the decay of the place. Pop. 1015.
