Beausoleil, Alpes-Maritimes

Commune in Provence Alpes Côte d'Azur, France

Beausoleil (bosɔlɛj; ; ) is a commune in the Alpes Maritimes department in the Provence Alpes Côte d'Azur region in Southeastern France. It adjoins the Principality of Monaco to its south. The commune of Beausoleil was established in 1904; it was supposed to be named Monte Carlo Supérieur (mɔ̃t kaʁlɔ sypeʁjœʁ; ) for a time but the idea was abandoned after protests from Monégasque authorities.

Located on a hillside above the city state of Monaco, Beausoleil is surrounded by the Tête de Chien and Agel mountains. It is urbanistically contiguous with the principality and shares some streets, as the Boulevard de France, the Boulevard du Maréchal Leclerc, and the Avenue du Maréchal Foch. Its municipality borders with the Monégasque wards of Monte Carlo, Saint Roman, Saint Michel, Moneghetti and Les Révoires; and with the French municipalities of La Turbie, Roquebrune Cap Martin and Peille.

The commune is intertwined with Monaco. It functions to some extent as a bedroom community as many of its residents are employed in Monaco. The main part of the town consists of Belle Époque houses with ornate entrances. Attractions within Beausoleil include the Gustave Eiffel covered market, St Joseph's Sanctuary (a church with ornate stained glass windows) and the Fontdivina Fountain and Wash House.

The town's border with Monaco was largely fixed during the 18th century. What is now known as Beausoleil was administered from La Turbie prior to 1904, when the town was incorporated. Along with other French communes adjacent to Monaco, the electorate has traditionally had a sizable proportion which is left leaning: Roger Bennati, mayor of the town 1989–1995, served under Communist affiliation. Monaco's political parties are more right leaning.

The Gare de Monaco Monte Carlo is located on the border between Beausoleil and Monaco.
