The Alliance française (French pronunciation: [aljɑ̃s fʁɑ̃sɛz], French Alliance), or AF, is an international organisation that aims to promote French language and culture around the world. Created in Paris on 21 July 1883, its primary concern is teaching French as a second language and is headquartered in Paris.

The Alliance was created in Paris on 21 July 1883 by a group of eminent men, including the scientist Louis Pasteur, the diplomat Ferdinand de Lesseps, the writers Jules Verne and Ernest Renan, and the publisher Armand Colin.

It finances most of its activities from the fees it receives from its courses and from rental of its installations. The French government also provides a subsidy covering approximately five percent of its budget (nearly 665,000 € in 2003)

More than 440,000 students learn French at one of the centres run by the Alliance, whose network of schools includes:

The organisations outside Paris are local, independently run franchises. Each has a committee and a president. The Alliance française brand is owned by the Paris centre. In many countries, the Alliance française of Paris is represented by a Délégué général. The French Government also run 150 separate French Cultural Institutes, that exist to promote French language and culture.
