Montenegro uses the euro (EUR) as its official currency. Although Montenegro is not a member of the European Union or the Eurozone and does not have a formal monetary agreement with the EU, it unilaterally adopted the euro in 2002 as its de facto domestic currency and legal tender. Prior to adopting the euro, Montenegro used the Deutsche Mark starting around 1999. The euro banknotes and coins used in Montenegro are the same as those circulating in Eurozone countries, but Montenegro does not have the authority to mint its own euro coins. In summary:

• Currency: Euro (EUR)
• Euro adopted unilaterally in 2002
• Not part of the EU or Eurozone
• Uses standard euro banknotes and coins already in circulation in Europe

This means prices in Montenegro are shown in euros, and the currency is divided into 100 cents, just like in Eurozone countries.
