Maalaiskunta (Finnish), landskommun (Swedish), "rural municipality", abbreviated mlk, was one of the four types of municipality in Finland in 1865–1976. Other types in 1865–1959 were city and market town, in 1960–1976 old city, new city and market town. Maalaiskunta was the most common type of municipality. In the 1977 reform, all municipalities were given fully equal legal standing. Previous maalaiskuntas associated with a city retained their name. For example, Rovaniemen maalaiskunta surrounded the city of Rovaniemi, but were independently governed.
