Carrefour Express is a convenience store chain owned and operated by French retailer Carrefour with locations in three continents. Carrefour Express was created in 2007 to consolidate all convenience stores owned by Carrefour worldwide under one name. In 2010, all convenience store operations in France, including Marché Plus, Champion and Shopi were rebranded as Express.

In 2007, the Carrefour Express concept was created to replace almost everywhere in the world the convenience stores owned by the Carrefour Group in locations that have small retail areas. These include Champion, Norte, GB, Globi and Gima.

Belgian retail chain GB opened its first convenience store, GB express, in 1997. In 2000 Carrefour acquired GB from the GIB Group. In 2007 all GB Express locations were rebranded as Carrefour Express.

In France, the chain's goal is to replace all convenience stores owned by Carrefour, that could not be converted to either Carrefour City or Carrefour Contact.

In December 2010, the first Carrefour Express was created in Caen, and a second in January 2011 in Poitiers, the third opened in the 5th arrondissement of Paris.

In April 2013, there were 252 Carrefour Express stores in France. In August 2013, 272 stores.

In Italy, the chain Dì per Dì was acquired from Promodès in 2007 and starting late 2009, was rebranded Carrefour Express as part of Carrefour's international reorganization.

Carrefour entered the Romanian market after acquiring local retail chain Artima for €52 million in October 2007, with the rebranding taking place in September 2008, nearly a year later. As of 30 December 2013, Carrefour operates 56 supermarkets in Romania.
