Funen (Dan. Fyen), an island of Denmark, having on the N. the S. W. prolongation of the Cattegat, E. the Great Belt, W. the Little Belt, and S. the archipelago connecting the two Belts; area about 1,160 sq. m.; pop. in 1870, 217,2-44, including the inhabitants of a number of small islands which come under its administration. It is the largest of the Danish isles after Seeland, and forms with the islands W. of the Great Belt, including Langeland and Arro, a circle of the kingdom. The coast is not very elevated, but is in general rugged and steep, and much indented by bays and arms of the sea. The interior toward the west is somewhat hilly; in every other direction it is composed of large and fruitful plains, which produce abundant crops of corn. The largest stream in the island is the Odense Aa, which has a northerly course of 36 m., and discharges into the Odense fiord, about 9 m. long, and from 1 1/2 to nearly 5 m. wide. A canal, navigable by vessels drawing 8 ft., connects the town of Odense with the Odense fiord. The largest lake is the Arreskov, which is about 7 m. in circuit, and abounds in fish.

Funen is divided into the bailiwicks of Odense, which contains the capital, of the same name, and Svendborg.
