The franc was the currency of French Guiana until 2002. The French franc circulated alongside banknotes issued specifically for French Guiana between 1888 and 1961 and notes issued for French Guiana, Guadeloupe and Martinique (collectively referred to as the French Antilles) between 1961 and 1975.
As an integral part of France, French Guiana is part of the European Union and the Eurozone, and starting in 2002, its currency is the euro.
