GIB Group (Grand Bazar Innovation Bon Marché) was a Belgian conglomerate, consisting of various retail and restaurant chains that existed until 2002. GIB Group owned GB (Grand Bazar) super/hypermarkets, Brico (home improvement/DIY), Inno (department store), Quick restaurants (Belgium, France, Netherlands, Luxembourg), Lunch Garden self-service restaurants, Auto 5 car wash/service chain, Nopri, GIB Immo, Christiaensen and Unic.

In 1860, the GIB Group is created by opening the first Au Bon Marché store in Brussels by François Vaxelaire.

In 1933, Nopri department stores were created.

In 1958, the first Super GB supermarket is opened.

In 1960, Baron François Vaxelaire (grandson of namesake) takes over the family business from his father, Raymond Vaxelaire.

In 1961, the first GB hypermarkets are created under the name of Superbazar in Auderghem, Anderlecht and Bruges. The Superbazar stores all became Maxi GB in 1985.

In 1969–74, Baron François Vaxelaire engineers a fusion of GB, Innovation and BM as GIB (GB-Inno-BM). Inno was a previously independent Belgian department store chain that was taken over (it is currently owned by Galeria Kaufhof).

In 1979, GIB and British supermarket chain Sainsbury's founded a garden retailer that would later become Homebase.
