The Ravillou is a 13 km long river in the Dordogne department, France.

It is a right tributary of the Loue, part of the Dordogne basin.

[1] The river rises in the commune of Dussac and runs through Saint-Germain-des-Prés before emptying into the Loue northwest of Coulaures.

On the night of June 13 and 14, 2007, a flash flood caused by a storm turned the Ravillou and its tributary the Merdanson into devastating torrents, that damaged the town of Saint-Germain-des-Prés and the bridge across the Ravillou.
