Beaujeu (French pronunciation: [boʒø]; Occitan: Bèujuec) is a commune in the Alpes-de-Haute-Provence department in the Provence-Alpes-Côte d'Azur region of south-eastern France.

[5][6] An enormous number of streams rise all over the commune which mostly converge on the Arigéol which flows south to join the Bléone at La Javie.

[8] The town was subject to several natural disasters, including flooding, mudslides, and landslides in 1986, 1994, and 1996.

[15] In Ancient times the Bodiontici populated the Bléone valley as well as the Gauls who lived in the current commune of Beaujeu.

The Bodiontici were defeated by Augustus at the same time as the other people present on the Tropaeum Alpium before 14 BC.

The Church of Saint Peter was originally built higher and the priory depended on the Augustinian Abbey of Valence.

[13][17] The locality appears for the first time in charters of 1147 (Beljog),[18] and a Motte-and-bailey castle was built in the 11th century at a place called La Tour.

[20] A toll was established on the Col de Labouret road at the end of the Middle Ages.

[22] The death of Queen Joanna I of Naples reopened a crisis of succession to head the county of Provence and the cities of the Union of Aix (1382-1387) supported Charles, Duke of Durazzo, against Louis I of Anjou.

After the failure of the uprising there was a severe crackdown on those who stood up to defend the Republic which included one inhabitant of Beaujeu.
