The Renault 9 and Renault 11 are small family cars produced by the French manufacturer Renault from 1981–1988 in saloon and hatchback configurations — both were styled by the French automobile designer, Robert Opron.

The C-segment is the 3rd category of the European segments for passenger cars and is described as "medium cars". It is equivalent to the Euro NCAP "small family car" size class, and the compact car category in the United States.
