The Siagne is a short river that flows through the Var and Alpes-Maritimes departments, in southeastern France.
The Siagne starts on the south side of the Audibergue mountain, in the commune of Escragnolles, Alpes-Maritimes department, at an elevation of about 1,367 m (4,485 ft). It then flows to the southwest through the departments of Alpes-Maritimes and Var. For much of its length, it forms the border between the two departments.
Finally, the river flows into the Mediterranean Sea at the city of Mandelieu-la-Napoule.
