Furnes is a former municipality in the old Hedmark county, Norway. The 200.5-square-kilometre (77.4 sq mi) municipality existed from 1891 until its dissolution in 1964. The area is now part of Ringsaker Municipality in the traditional district of Hedmarken. The administrative centre was the village of Furnes where the Furnes Church is located.

Prior to its dissolution in 1964, the 200.5-square-kilometre (77.4 sq mi) municipality was the 370th largest by area out of the 689 municipalities in Norway. Furnes Municipality was the 111th most populous municipality in Norway with a population of about 7,169. The municipality's population density was 35.8 inhabitants per square kilometre (93/sq mi) and its population had increased by 17.6% over the previous 10-year period.

The municipality of Furnes was established in 1891 when the old Vang Municipality was divided into two: Furnes Municipality in the west (population: 3,790) and Vang Municipality in the east (population: 5,703). In 1947, a part of Furnes Municipality (population: 821) near the town of Hamar was transferred from Furnes Municipality to Hamar Municipality.

During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, the following areas were merged to form a new, larger Ringsaker Municipality:

The municipality (originally the parish) is named after the old village of Furnes (Old Norse: Furnes) since the first Furnes Church was built there. The first element of the name has an unknown meaning, but it may have come from a local river such as Fura. Another possibility is that it comes from the word furu which means "pine tree" or "fir tree". The last element is nes which means "headland".

The Church of Norway had one parish (sokn) within Furnes Municipality. At the time of the municipal dissolution, it was part of the Furnes prestegjeld and the Hamar domprosti (arch-deanery) in the Diocese of Hamar.

Furnes Municipality was located in the Hedmarken district to the northeast of the large lake Mjøsa. Åmot Municipality was located to the north, Vang Municipality was located to the east, Hamar Municipality was located to the south, Nes Municipality was located to the southwest, and Ringsaker Municipality was located to the west. The highest point in the municipality was the 950-metre (3,120 ft) tall mountain Kroksjøhøgda in the far northern part of the municipality.

While it existed, Furnes Municipality was responsible for primary education (through 10th grade), outpatient health services, senior citizen services, welfare and other social services, zoning, economic development, and municipal roads and utilities. The municipality was governed by a municipal council of directly elected representatives. The mayor was indirectly elected by a vote of the municipal council. The municipality was under the jurisdiction of the Eidsivating Court of Appeal.
