Fusine in Valromana (Slovene: Fužine or Bela Peč;[1] German: Weißenfels;[1][2] Friulian: Fusinis) is a frazione (fractional parish) of the comune of Tarvisio in the Province of Udine, in the autonomous Friuli-Venezia Giulia region of northeastern Italy.

The hamlet is located in the western Julian Alps, about 8 km (5.0 mi) east of the Tarvisio town centre and close to the tripoint where the borders of Slovenia, Austria, and Italy meet.

Upper and Lower Lakes Fusine fed by artesian springs on the north face of the 2,677 m (8,783 ft) high Mangart peak attract many tourists.

Unlike the neighbouring villages to the west, this easternmost part of the Canale Valley was not included in the Carinthian possessions of the Prince-Bishops of Bamberg, granted to them by King Henry II of Germany in 1007, but belonged to the Counts of Ortenburg and was under the suzerainty of the Landgraves, later Dukes of Carniola.

In 1404, the reigning Ortenburg count Frederick III gave one Consuran Bartholomew the right to build a forge, which established the iron industry and promoted the settlement of German-speaking workers.
