Lithuania

Explanation:

[STC001908] If you’re on a European vacation and looking to spend your last handful of euros, you can now do so in Lithuania, the most recent European Union country to adopt the currency. It wasn’t until 2004 that Lithuania became the last of the Baltic states to join the European Union, and it wasn’t until 2015 that it started utilizing the euro. (Estonia made the transition to utilizing the euro in 2011, whereas Latvia didn’t start doing so until 2014) It is presently one of the 19 countries that make up the so-called eurozone. The remaining eight EU member states have either not yet qualified or have chosen not to participate.
