The Varagno (French: Ruisseau de ´Varagno) is a stream in the department of Haute-Corse, Corsica, France.

[1] The stream, known in its upper section as the Ruisseau d'Albarelli, rises to the east of the 1,769 metres (5,804 ft) Punta di Taoria.

[2] The Varagno flows through the Forêts du Fiumorbu, designated as a Zone naturelle d'intérêt écologique, faunistique et floristique (ZNIEFF).

This includes the upper and middle watershed of the Abatesco and tributaries of the Fium'Orbu river such as the Saltaruccio and Varagno streams.

Lower down there are stands of maritime pines (Pinus pinaster) and holm oaks (Quercus ilex).
