The Fium'Alto (or Fium'Altu) is a small coastal river in the department of Haute-Corse, Corsica, France.

The Fium'Alto is 30.81 kilometres (19.14 mi) long. It crosses the communes of Carcheto-Brustico, Casalta, Croce, Ficaja, Monacia-d'Orezza, Penta-di-Casinca, Piano, Piazzole, Piedicroce, Piedipartino, Pie-d'Orezza, Porri, La Porta, Pruno, Rapaggio, Scata, Stazzona, San-Damiano, San-Gavino-d'Ampugnani and Taglio-Isolaccio.^[1]

The Fium'Alto rises to the south of the 1,767 metres (5,797 ft) Monte San Petrone in the commune of Pie d'Orezza. It flows southeast past the village of Pie d'Orezza, east past Piedicroce and Stazzona, then generally north and east to the town of Folelli (Penta-di-Casinca) and the sea. The D71 road follows the upper part of the river, and then the D506 follows it for the remainder of its course.^[2]

Measurements of the river flow were taken at the Taglio-Isolaccio Acitaja station from 1960 to 2021. The watershed above this station covers 114 square kilometres (44 sq mi). Annual precipitation was calculated as 383 millimetres (15.1 in). The average flow of water throughout the year was 1.38 cubic metres per second (49 cu ft/s).^[3]
