The króna (Icelandic pronunciation: [ˈkʰroːuna]; plural krónur) (sign: kr; code: ISK) is the currency of Iceland. The króna was historically subdivided into 100 aurar (singular eyrir), but this subdivision is no longer used.

Like the Nordic currencies (such as the Danish krone, Swedish krona and Norwegian krone) that participated in the historical Scandinavian Monetary Union, the name króna (meaning crown) comes from the Latin word corona ("crown"). The name "Icelandic crown" is sometimes used, for example in the financial markets. The word eyrir derives from Latin aureus ("golden"), there being historically 100 gold pieces to a crown.
