Saint-Nazaire (French: [sɛ̃ nazɛːʁ] ; Breton: Sant-Nazer/Señ Neñseir; Gallo: Saint-Nazère/Saint-Nazaer) is a port town and commune in the Loire-Atlantique department in western France, in traditional Brittany.
The town has a major harbour on the right bank of the Loire estuary, near the Atlantic Ocean. The town is at the south of the second-largest swamp in France, called "la Brière". Given its location, Saint-Nazaire has a long tradition of fishing and shipbuilding. The Chantiers de l'Atlantique, one of the largest shipyards in the world, constructed notable ocean liners such as SS Normandie, SS France, RMS Queen Mary 2 and the cruise ship MS Symphony of the Seas, the largest passenger ship in the world until 2022.
