This chapter aims to provide an overview of the European regions or countries, outside France, where French has the status of official language: Wallonia and Brussels in Belgium, Romandy in Switzerland, the Aosta Valley in Italy, and Luxembourg. They all have in common the fact that they are multilingual and share territorial borders with eastern France. For historical reasons, the development of French cannot be considered independently in these four regions/countries and in France, even though they now belong to five countries with different language policies. Because the role and the situation of French in the multilingual landscapes of the four countries/regions are quite different, the chapter considers them separately and, for each of them, it first presents the demo-linguistic and historical context, before describing the actual situation of French and its linguistic and sociolinguistic aspects.
