The official currency of the Czech Republic is the Czech Koruna (plural: koruny), often abbreviated as CZK or referred to locally by the symbol Kč. Despite being a member of the European Union, the Czech Republic has not yet adopted the Euro. In 2026, the koruna remains the only legal tender for daily transactions, and while some large hotels or tourist-heavy shops in Prague might display prices in Euros, they often use a poor exchange rate, so it is always better to pay in the local currency. Banknotes come in denominations of 100, 200, 500, 1,000, 2,000, and 5,000 Kč, while coins are available in 1, 2, 5, 10, 20, and 50 Kč. Most travelers in 2026 find that the Czech Republic is a very "card-friendly" country, with contactless payments accepted at almost all restaurants, shops, and even for public transport in Prague. However, it is still useful to have a few small coins for public restrooms or smaller vendors in rural areas. When using an ATM, always select "Withdraw without conversion" to let your home bank handle the exchange rate, avoiding the high fees often charged by third-party terminal operators like Euronet.
