Regional elections were held in France on 6 and 13 December 2015. At stake were the regional councils in metropolitan and overseas France including the Corsican Assembly and inaugural seats in the Assembly of French Guiana and Assembly of Martinique, all for a six-year term. The Departmental Council of Mayotte, which also exercises the powers of a region, was the only region not participating in this election, having already been renewed on 2 April 2015. There were 18 regional presidencies at stake, with 13 in mainland France and Corsica, as well as 5 overseas. Though they do not have legislative autonomy, these territorial collectivities manage sizable budgets. Moreover, regional elections are often taken as a mid-term opinion poll.
These elections were the first to be held for the redrawn regions: the 27 regions of France were amalgamated into 18, this went into effect on 1 January 2016.
