Which country was the last to adopt the euro as of 2024?

Croatia was the last country to adopt the euro as of 2024, introducing it on 1 January 2023.

The change made Croatia the eurozone’s 20th member and ended the use of the Croatian kuna as the country’s official currency. Croatia had joined the European Union in 2013 and entered the Exchange Rate Mechanism II in July 2020, a required step before euro adoption. Its fixed conversion rate was set at €1 = 7.53450 kuna.

Croatia also joined the Schengen Area on the same date, making 1 January 2023 a major milestone in its European integration. Prices were displayed in both currencies during the transition, and kuna cash circulated alongside euros for the first two weeks of January.

A common mix-up is Lithuania, which became the eurozone’s 19th member in 2015. Bulgaria and Romania had not adopted the euro by the end of 2024, so neither could be the answer.
