the French/Italian/English Riviera a warm coast that is popular with people who are on holiday, especially the Mediterranean coast of France. Coastal region bordering the Mediterranean Sea in southeastern France, Monaco, and northwestern Italy. It extends from Cannes, France, to La Spezia, Italy. The Italian Riviera is divided into the Riviera di Ponente, west of Genoa, and the Riviera di Levante, east of Genoa. The French Riviera is also called the Côte d'Azur.
