The euro banknotes are the banknotes of the euro, the currency of the Eurozone and have been in circulation since 2002. They are issued by the National Central Banks of the Eurosystem or the European Central Bank. Denominations of the notes range from €5 to €500 and, unlike euro coins, the design is identical across the whole of the eurozone, although they are issued and printed in various member states.

The euro came into existence on 1 January 1999, although it had been a goal of the European Union (EU) and its predecessors since the 1960s. After tough negotiations, particularly due to opposition from the United Kingdom, the Maastricht Treaty entered into force in 1993 with the goal of creating economic and monetary union by 1999 for all EU states except the UK and Denmark (even though Denmark has a fixed exchange rate policy with the euro).

In 1999 the currency was born virtually and in 2002 notes and coins began to circulate. It rapidly took over from the former national currencies and slowly expanded behind the rest of the EU. In 2009 the Lisbon Treaty formalised its political authority, the Euro Group, alongside the European Central Bank.
