Falster, an island of Denmark, in the Baltic, S. of Seeland, separated from the island of Moen on the northeast by Gron sound, and from that of Laaland on the west by Guld-borg sound, and forming part of the bailiwick of Maribo; area, including the little island of Hasselo, 181 sq. m.; pop. in 1870, 25,000. In the northeast it is mountainous, and elsewhere entirely flat. On account of its abundant fruits, it is called the orchard of Denmark. Grain, flax, hemp, hops, honey, and wax are the principal products. Cattle, hogs, and poultry abound, and peat, chalk, and building stone are found. The chief town, Nykiobing, contains a castle and cathedral, and has an active trade; pop. in 1870, 3,645. Originally in possession of Danish nobles, the island passed into that of the royal family, and a number of Danish queens resided in its capital in the 16th and in the early part of the 17th century.
