The krone (alternatively crown) was the official currency of Austria-Hungary from 1892 (when it replaced the gulden as part of the adoption of the gold standard) until the dissolution of the empire in 1918. The subunit was one hundredth of the main unit, and was called a 'heller' in the Austrian and a 'fillér' in the Hungarian part of the Empire.

The official name of the currency was krone in Austria and korona in Hungary. The Latin form 'Corona' (plural 'Coronæ'), abbreviated to 'Cor.' on the smaller coins, was used for the coinage of the mostly German-speaking part of the empire known as Cisleithania.

After several earlier attempts the Austro-Hungarian Empire adopted the gold standard in 1892 according to a plan drawn up by the Hungarian Minister of Finance Sándor Wekerle. This plan included the introduction of the new currency, the Krone.
