Stange^ⓘ is a municipality in Innlandet county, Norway. It is located in the traditional district of Hedmarken. The administrative centre of the municipality is the village of Stangebyen. Other villages include Bekkelaget, Espa, Bottenfjellet, Ilseng, Ottestad, Sandvika, Sinnerud, Starhellinga, Tangen, and Romedal.

The 724-square-kilometre (280 sq mi) municipality is the 157th largest by area out of the 357 municipalities in Norway. Stange Municipality is the 60th most populous municipality in Norway with a population of 21,691. The municipality's population density is 29.5 inhabitants per square kilometre (76/sq mi) and its population has increased by 9.5% over the previous 10-year period.

The parish of Stange was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, Romedal Municipality (population: 6,441) and Stange Municipality (population: 9,734) were merged to form a new, larger Stange Municipality with a population of 16,175 residents. On 13 July 1956, a small part of the neighboring Vang Municipality (population: 24) was transferred to Stange Municipality.

Historically, the municipality was part of the old Hedmark county. On 1 January 2020, the municipality became a part of the newly-formed Innlandet county (after Hedmark and Oppland counties were merged).

The municipality (originally the parish) is named after the old Stange farm (Old Norse: Stangir) since the first Stange Church was built there. The name is the plural form of stǫng which means "bar", "pole", or "rod". (The farm is lying on a long hill, and this is probably the background for the name.)

The coat of arms was granted on 20 June 1986. The official blazon is "Vert, a plough argent" (Norwegian: I grønt en sølv ard). This means the arms have a green field (background) and the charge is a medieval plough called an ard. The charge has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used. The design symbolizes this historic importance of agriculture in the area; originally the growing of grains and then later growing potatoes. The arms were designed by Arne Løvstad. The municipal flag has the same design as the coat of arms.

The Church of Norway has five parishes (sokn) within Stange Municipality. It is part of the Hamar domprosti (arch-deanery) in the Diocese of Hamar.

The newspaper Stangeavisa has been published in Stange since 2004.
