Skellefteå Municipality is a municipality in Västerbotten County in northern Sweden. Its seat is located in Skellefteå. Most of the amalgamations leading to the present municipality took place in 1967 when the then "City of Skellefteå" was merged with the rural municipality by the same name and also with the municipalities Jörn, Bureå and Byske. The enlarged city became a municipality of unitary type with the new local government act in 1971, and in 1974 the municipalities Burträsk and Lövånger were added.
