The National Bank of Czechoslovakia (Czech: Národní banka Československá) was the central bank of Czechoslovakia between 1926 and 1939, succeeding the Austro-Hungarian Bank after a 6-year interval during which central banking functions were assumed directly by the country’s ministry of finance.
Between 1939 and 1945, its activities were divided into the National Bank for Bohemia and Moravia in Prague (Czech: Národní banka pro Čechy a Moravu v Praze, German: Nationalbank für Böhmen und Mähren in Prag) in the Protectorate of Bohemia and Moravia and the Slovak National Bank (Slovak: Slovenská Národná Banka) in the Slovak Republic. The National Bank was re-established in reunified Czechoslovakia in 1945, and in 1950 renamed State Bank of Czechoslovakia (Czech: Státní banka československá, Slovak: Štátna banka československá).
On 1 January 1993, the State Bank of Czechoslovakia was replaced by its two successor entities, the Czech National Bank in the Czech Republic and the National Bank of Slovakia in Slovakia.
