The Mercedes-Benz C-Class (W203) is the internal designation for a range of compact executive cars manufactured and marketed by DaimlerChrysler from 1999 to 2010, as the second generation of the C-Class — in sedan/saloon, three-door hatchback coupé and station wagon/estate body styles.

The Mercedes-Benz C-Class is a series of compact executive cars produced by Mercedes-Benz Group AG. Introduced in 1993 as a replacement for the 190 (W201) range, the C-Class was the smallest model in the marque's line-up until the W168 A-Class arrived in 1997. The C-Class has been available with a "4MATIC" four-wheel drive option since 2002. The third generation (W204) was launched in 2007 while the current W206 generation was launched in 2021.
