Jokkmokk Municipality (Jokkmokks kommun, Jokimukan kunta, Johkamohkki gielda, Jokinmukka) is a municipality in Norrbotten County in northern Sweden. Its seat is located in Jokkmokk.
The name Jokkmokk is Sami for the words "river" and "bend", since the town is situated close to a bend in the nearby river.
The municipality is the second largest in area of all Swedish municipalities and is, with an area of 19,477 km2 (approximately 7,520 square miles) slightly smaller than Slovenia or the US state of New Jersey. It has never been amalgamated with another entity, having been that large ever since municipalities were established in Sweden in 1863.
The name Jokkmokk is present in the Jokkmokk Lapland Court District, a historical jurisdiction. When the municipality was given its current borders in 1971, its municipal coat of arms were made to depict the hydro plant, the symbol of Luleå (to which Jokkmokk belonged until 1673), and the traditional Sami hammers.
