The Renault Laguna is a large family car produced by the French manufacturer Renault. The first Laguna was launched in 1993, the second generation was launched in 2000, and the third generation was made available for sale in October 2007. On December 19, 2011 Renault announced the Laguna line would be discontinued as part of a cost cutting plan to help the company earn a profit.

The regular production Renault passenger models are unrelated to the concept car of the same name, the Laguna, a two-seat roadster shown by the automaker during the European 1990 auto show circuit. The name was also previously used from 1973 to 1976 by Chevrolet for a top-of-the-line Chevelle model, the Chevrolet Chevelle Laguna.
