Aostan French (French: français valdôtain) is the variety of French spoken in the Aosta Valley, Italy.
The Aosta Valley was the first government authority to adopt Modern French as working language in 1536, three years before France itself. French has been the official language of the Aosta Valley since 1561, when it replaced Latin. In the 1861 census, the first held after the unification of Italy, 93% declared being Francophone; in 1921, the last census with a question about language found that 88% of the population was French-speaking. The suppression of all French-language schools and institutions and violence against French speakers during the forceful Italianisation campaign of the Fascist government irretrievably damaged the status of French in the region. Italian and French are nowadays the region's official languages and are used for the regional government's acts and laws, though Italian is much more widely spoken in everyday life, and French is mostly used by intellectuals and within cultural events. Though French was re-introduced as an official language after World War II, by 2003 just 0.99% reported speaking standard French natively. French remains widely known as a second language, but it is no longer spoken as part of daily life. In 2001, 75.41% of the population of Aosta Valley was French-speaking, 96.01% declared to know Italian, 55.77% Franco-Provençal, and 50.53% all of them. School education is delivered equally in both Italian and French so that everyone who went to school in Aosta Valley can speak French to at least at a medium-high level.
Aostan French is characterized by terms adopted from the patois francoprovençal valdôtain and sometimes from Italian. In this sense, it is quite similar to Savoyard dialect and to valaisan dialect as spoken in Valais.
