The Rivière des Pluies is a river on the Indian Ocean island of Réunion. It flows to the sea on the island's northern shore, between the communes of Saint-Denis and Sainte-Marie. It is 18.5 km (11.5 mi) long.

It gives its name to a district of Sainte-Marie that overlooks the river, and is inhabited by many people working in the capital.

Rivière des Pluies is crossed by five bridges, from upstream to downstream.

• A bridge carrying a water supply canal.
• Desbassyns bridge, a road bridge carrying the main road 45.
• The Pont Neuf, a road bridge carrying the highway 102.
• A road bridge on Route Nationale 6, the most recent.
