Kiruna Municipality (Swedish: Kiruna kommun; Northern Sami: Giron gielda; Meänkieli: Kierunan kunta; Finnish: Kiirunan kunta) is a municipality in Norrbotten County in northernmost Sweden.

Finnish, Meänkieli and Sami have the official status of being minority languages in the municipality.

During the 20th century, the mining settlement Kiruna was built in the parish of Jukkasjärvi, at that time a rural municipality in very remote territory.

A so-called municipalsamhälle (which was a kind of borough established within a rural municipality to take care of some matters of urban character) was instituted in 1908.

As the vast wilderness around the town itself was included, Kiruna was at that time regarded as the largest city municipality in the world.

Kiruna has high general incomes for an isolated municipality in northern Sweden, mainly as a result of the vast mining industry.
