Maalselven was established in 1849 when it was separated from the municipality of Lenviken. The initial population of Maalselven was 2,616. In 1891, some parts of the Målsnes area (population: 30) were transferred to neighboring Malangen. On 1 January 1904, an area with 5 inhabitants was transferred from Balsfjord to Maalselven. The spelling of the name was changed to Målselv in 1918. On 1 July 1925, the district of Øverbygd was separated from Målselv to form a new municipality of its own. This left Målselv with 3,531 residents.
