Plage de Sainte-Marguerite, Sandy beach and sports venue in Pornichet, France

Plage de Sainte-Marguerite is a public sand beach in Pornichet, Loire-Atlantique, one of the town's three sandy beaches alongside Les Libraires and Bonne-Source. It runs 1.5 km, from the Pointe de Congrigoux, which separates it from Bonne-Source, southeast to the Pointe de la Lande at the town boundary. A broad tan sand band widens toward the buildings and trees at its upper edge, with shallow waves along the water.

The Sainte-Marguerite subdivision was created in 1886 by Charles Mercier, who named it after his daughter. The beach takes its name from this development and lies within the commune of Pornichet, one of its three sandy beaches alongside Les Libraires and Bonne-Source.
