Inari (Finnish pronunciation: [ˈinɑri]; Inari Sami: Aanaar; Skolt Sami: Aanar; Northern Sami: Anár [ˈanaːr]; Norwegian and Swedish: Enare) is Finland's largest municipality by area (but one of the most sparsely populated), with four official languages, more than any other in the country. Its major sources of income are tourism, the service industry and cold climate testing. With the Siida museum in the village of Inari, it is a center of Sami culture, widely known as the "capital of Sámi culture".

The airport in Ivalo and the country's key north-south European Route E75 (Finland's National Road 4) bring summer and winter vacationers seeking resorts with access to a well-preserved, uncrowded natural environment.

Inari is the largest municipality by area in Finland. Located in Lapland, it covers an area of 17,333.65 square kilometres (6,692.56 sq mi), of which 2,281.41 km2 (880.86 sq mi) is water. With an area of 1,043 km2 (403 sq mi), Lake Inari is the third largest lake in Finland, 40 km2 (15 sq mi) smaller than the country's second-largest Lake Päijänne.

Finland's largest National Park Lemmenjoki is partly located in Inari, as is the Urho Kekkonen National Park. Vast parts of the municipality are designated wilderness areas: Hammastunturi, Muotkatunturi, Paistunturi, Kaldoaivi, Vätsäri, and Tsarmitunturi.
