The Poggiolo (French: Ruisseau de Poggiolo, Corsican: Fiume di Poggiolu) is a small coastal stream in the department of Haute-Corse, Corsica, France. It enters the Tyrrhenian Sea from the east of the Cap Corse peninsula.

The Poggiolo is 6.94 kilometres (4.31 mi) long and flows through the communes of San-Martino-di-Lota and Santa-Maria-di-Lota. The stream rises in the Serra di Guagalone. Its source is to the east of the 1,198 metres (3,930 ft) U Cimone. It flows south and then east past the village of Santa-Maria-di-Lota to enter the sea in the village of Miomo. Its mouth is south of the Miomo pebble beach.

For thirteen centuries the coasts of Corsica were at risk of being raided. The Genoese built a tower, the Torra di Miomu, near the mouth of the Poggiolu to guard its valley.

Along its banks there are ash trees, alders, hornbeams, hops and chestnut trees. The stream is populated with brown trout (Salmo trutta).
