Charte de la langue française

The Charter of the French Language (French: La charte de la langue française), also known as Bill 101 (Law 101 or French: Loi 101), is a 1977 law in the province of Quebec in Canada defining French, the language of the majority of the population, as the official language of Quebec. It is the central legislative piece in Quebec's language policy.

Proposed by Camille Laurin, the Minister of Cultural Development under the first Parti Québécois government of Premier René Lévesque, it was passed by the National Assembly, and granted Royal Assent by Lieutenant Governor Hugues Lapointe on August 26, 1977. The Charter's provisions expanded upon the 1974 Official Language Act (Bill 22), which was enacted by the Lieutenant Governor-in-Parliament during the tenure of Premier Robert Bourassa's Liberal government to make French the official language of Quebec. Prior to 1974, Quebec had no official language and was subject only to the requirements on the use of English and French contained in Article 133 of the British North America Act, 1867.

Bill 101 has been amended more than six times since 1977. Each amendment has aroused controversy over such provisions as the use of French on commercial signs or restrictions on enrollment into anglophone schools.
