The Citroën C-Triomphe is a mid-size sedan produced for the Chinese market by Dongfeng Peugeot-Citroën, a joint venture between the French PSA Group (Peugeot-Citroën) and the Chinese manufacturer Dongfeng.

In April 2007, Citroën announced that the four-door C4 would be built in Argentina.

The Argentinian and Brazilian versions are sold as the C4 Pallas in some South American and European markets.

This caused the C-Triomphe sedan to be classified in large family car class.

The C-Triomphe has a number of unique features, such as an integrated air freshener which allows the driver to choose the smell of the interior.
