Champion was a supermarket chain that operated in France and owned by the international retailer Carrefour. There were also Champion supermarkets in Belgium, Spain, Poland, Greece, Turkey, Argentina and Brazil.

In 1993, Champion became the main sponsor of the polka dot jersey in the Tour de France until 2008. From 2009, Carrefour took over the sponsorship.

In 1999, Champion is taken over by the Carrefour Group after the fusion of Promodès and Champion grows by absorbing the Stoc chain.

In 2006, Carrefour closed most Brazilian Champion stores and rebranded the remainder to the Carrefour Bairro. Also, all Spanish and Turkish Champion supermarkets were rebranded as Carrefour Express in 2006; some of them became Maxi DIA.

In 2008, Champion was the second largest supermarket chain in France, its annual turnover was €13.5bn. There were over 1,000 stores and 45,000 employees.

In 2008, it was announced that most stores would be rebranded to Carrefour Market between September 2008 and October 2009.

In 2009, there were 135 supermarkets, in 2011 there were less than 100 stores.

By 2013, only two Champion stores were left in European France (excluding French overseas islands), in Paris (18th arrondissement) and in Pouzac. In 2018, after a legal battle filed against Carrefour was concluded, the last remaining (Paris) store was also rebranded, marking the end of the "Champion" supermarket brand in Europe.
