The French overseas départements are examples: Réunion and Mayotte (in the Indian Ocean), Guadeloupe and Martinique (in the Carribeans), and Guyane (in South America). There is also Saint Martin (French, but not a département), the Azores and Madeira (Portugal) and the Canaries (Spain). All these places are in the EU and use the Euro despite not being in Europe.
