Övertorneå Municipality (Swedish: Övertorneå kommun, Meänkieli: Matarengin kunta) is a municipality in Norrbotten County in northern Sweden, bordering Finland. Its seat is located in Övertorneå.
Until the Finnish War (1808–1809) Övertorneå and the Finnish Ylitornio were a single parish. Following the war, the eastern part of the municipality was ceded to Russia as a part of Finland. In 1870 a minor part of Övertorneå Municipality was split off, forming the rural municipality Korpilombolo (now part of Pajala Municipality). In 1969 Övertorneå and Hietaniemi municipalities were merged, forming the present municipality.
Many places in the municipality have both a Swedish and a Meänkieli name, one of the minority languages of Sweden.
