The Citroën C3 is a supermini car produced by Citroën since April 2002. It replaced the Citroën Saxo in the model line up, and is currently in its third generation. The third generation model made its appearance in June 2016, and went on sale in January 2017.

It is produced in a five door hatchback body style, with the first generation also being produced in a two door convertible version, called the C3 Pluriel. A three door hatchback, with a similar design as the second generation, marketed as a premium model, is available as the DS3.

A mini MPV version of the C3 was announced in July 2008, called the C3 Picasso, and was unveiled at the 2008 Paris Motor Show. In South America, a mini SUV version, called the C3 Aircross, is produced and marketed only locally. In October 2014, the Citroën C3 was awarded most efficient small cars, with the premium car DS 3.
