The Finnish markka was the currency of Finland from 1860 until 28 February 2002, when it ceased to be legal tender. The markka was divided into 100 pennies. At the point of conversion, the rate was fixed at €1 = 5.94573 mk.

The markka was replaced by the euro (€), which had been introduced, in cash form, on 1 January 2002. This was after a transitional period of three years when the euro was the official currency but only existed as "book money" outside of the monetary base. The dual circulation period, when both the Finnish markka and the euro had legal tender status, ended on 28 February 2002.

The name "markka" was based on a medieval unit of weight. Both "markka" and "penni" are similar to words used in Germany for that country's former currency, based on the same etymological roots as the German Mark and pfennig.
