The Bosnia and Herzegovina convertible mark is the currency of Bosnia and Herzegovina. It is divided into 100 pfenigs or fenings, and locally abbreviated KM. The convertible mark was established by the 1995 Dayton Agreement. It replaced the Bosnia and Herzegovina dinar, Croatian kuna and Republika Srpska dinar as the single currency of Bosnia and Herzegovina in 1998. Mark refers to the German mark, the currency to which it was pegged at par.

In December 1998, coins were introduced in denominations of 10, 20 and 50 fenings/pfenigs. Coins of 1, 2 and 5 marks were introduced later. The coins were designed by Bosnian designer Kenan Zekic and minted at the Royal Mint in Llantrisant (Wales, UK).

In 1998, notes were introduced in denominations of 50 fenings/pfenigs, 1 mark, 5, 10, 20, 50 and 100 marks. 200-mark notes were added in 2002, whilst the 50-fening/pfenig, 1- and 5-mark notes were later withdrawn from circulation. All current notes are valid throughout the country.
