The fifty euro note (€50) is one of the middle value euro banknotes and has been used since the introduction of the euro (in its cash form) in 2002. The note is used daily by some 332 million Europeans and in the 22 countries which have it as their sole currency (with 20 legally adopting it).

It is the fourth smallest note measuring 140x77mm and has an orange colour scheme. The fifty euro bank notes depict bridges and arches/doorways in the Renaissance era (between the 15th and 16th century).

The fifty euro note contains several complex security features such as watermarks, invisible ink, holograms and microprinting that document its authenticity. In September 2011, there were approximately 5,699,719,400 fifty euro banknotes in circulation in the Eurozone 17.

The fifty euro note is used daily by some 332 million Europeans and in the 22 countries which have it as their sole currency (with 20 legally adopting it). Both the European Central Bank and the central banks of the eurozone countries have the legal right to issue the 7 different euro banknotes. However, the national central banks of the zone physically issue and withdraw euro banknotes. The European Central Bank does not have a cash office and is not involved in any cash operations.

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.
