Vinger is a former municipality in the old Hedmark county, Norway. The 499-square-kilometre (193 sq mi) municipality existed from 1838 until its dissolution in 1964. The area is now part of Kongsvinger Municipality in the traditional district of Vinger in the southern part of the county, along the border with Sweden. The administrative centre of Vinger was located in the town of Kongsvinger where Vinger Church is located (the town was not actually part of the municipality, but this was where the councils met). Some villages in Vinger included Granli, Austmarka, and Skinnarbøl

Prior to its dissolution in 1963, the 499.2-square-kilometre (192.7 sq mi) municipality was the 201st largest by area out of the 689 municipalities in Norway. Vinger Municipality was the 132nd most populous municipality in Norway with a population of about 6,228. The municipality's population density was 12.5 inhabitants per square kilometre (32/sq mi) and its population had increased by 7.8% over the previous 10-year period.

The prestegjeld of Vinger was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). In 1854, the King issued a royal decree that declared the village area around the Kongsvinger Fortress to be a kjøpstad called Kongsvinger. On 7 February 1855, the town of Kongsvinger (population: 472) was separated from Vinger Municipality to become the new Kongsvinger Municipality (which was very small and just included the town itself). Afterwards, Vinger Municipality had a population of 10,947.

In 1864, the southern part of the municipality (population: 6,920) was separated from Vinger Municipality to form the new Eidskog Municipality. This division left Vinger Municipality with a population of 6,226. On 1 January 1876 a part of Vinger Municipality adjacent to the town of Kongsvinger containing 209 inhabitants was transferred to Kongsvinger Municipality.

During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, a large municipal merger took place, merging the following areas to form the new Kongsvinger Municipality with a total population of 12,990.

The whole region was historically called Vinger (Old Norse: Vingr) and this name was given to the municipality upon its creation in 1838. This name could be related to the river Glomma which flows through the region. One could compare this to the English word swing (for the missing s see Indo-European s-mobile). The river Glomma passes through the center of the district where the south-flowing river takes a sharp northwestward turn. This can be compared to the similar Lithuanian word vìngis which means "bend", "bow", or "turn".

The Church of Norway had one parish (sokn) within Vinger Municipality. At the time of the municipal dissolution, it was part of the Vinger prestegjeld and the Vinger og Odal prosti (deanery) in the Diocese of Hamar.

The municipality was located in the northern part of the traditional district of Vinger. The highest point in the municipality was the 460-metre (1,510 ft) tall point in the Fuglemyråsen area. Brandval Municipality was located to the north, Sør-Odal Municipality was located to the west, and Eidskog Municipality was located to the south. The town of Kongsvinger was an enclave located within Vinger Municipality. The Kingdom of Sweden was located to the east of Vinger Municipality and both Gunnarskog Municipality (present-day Arvika Municipality) and Fryksände Municipality (present-day Torsby Municipality) were located along the eastern border.
