Queenstown, a town of county Cork, Ireland, on the S. side of Great island, in the harbor and 7 m. E. S. E. of the city of Cork; pop. in 1871, 10,039. It is built on a steep acclivity, the streets rising one above another parallel to the beach, and the piers forming a fine promenade. A splendid Catholic cathedral is in course of erection (1875). The harbor is 3 m. long by 2 m. broad, with an entrance 2 m. long and 1 m. wide. It contains Spike island with Fort Westmoreland, artillery barracks, and a prison for 800 convicts, who are employed in the fortifications and in constructing a dockyard and basin on the adjoining island of Hawlbowline. This island contains a depot for ordnance and victualling stores, and near it is Rocky island, with barracks and powder magazines cut out of the rock. Queenstown is the station of the commanding admiral, of the royal yacht club, and of transatlantic steamers. A vast number of Irish emigrants embark here for the United States, and many passengers land here in preference to Liverpool. Previous to the wars with Napoleon I. it was a small village of fishermen; it then became important as a naval station.

It was known as the Cove of Cork until 1849, when the name was changed on occasion of Queen Victoria's visit.
