Yes, Croatia officially uses the euro as its sole legal tender. The country joined the Eurozone on January 1, 2023, replacing its previous currency, the kuna (HRK). By 2026, the transition is completely finalized, and the kuna is no longer accepted in daily commerce. Travelers can use euro banknotes and coins throughout the country, from the bustling markets of Zagreb to the seaside cafes of Dubrovnik. Croatia's entry into the Eurozone coincided with its entry into the Schengen Area, meaning that most travelers from within the EU can now visit without passport checks and without the need to exchange currency. While the kuna can no longer be used for shopping, the Croatian National Bank (Hrvatska narodna banka) continues to exchange old kuna banknotes for euros indefinitely, though the deadline for exchanging kuna coins passed at the end of 2025. For tourists, this change has made traveling through the Balkans significantly more convenient, eliminating the "hidden" costs of currency conversion fees.
