Kuopio is a city and a municipality located in the region of Northern Savonia, Finland. A population of 97,552 makes it the ninth biggest city in the country. The city has a total area of 2,317.24 square kilometres (894.69 sq mi), of which 719.85 km² (277.94 sq mi) is water and half forest. The population density is only 61 /km² (160 /sq mi), but the city's urban areas are populated very densely (urban area: 1 617.6 /km²), nationally second only to capital Helsinki (urban area: 1,690.0/km²). The population of the entire Kuopio region is 119,472.

There are several explanations behind the name Kuopio. The first is that in the 16th century, a certain influential person named Kauhanen in Tavinsalmi changed his name to Skopa and the people's pronunciation was Coopia and finally Cuopio. The second explanation is that it comes from the verb kuopia, meaning when, for example, a horse paws the ground with its hoof. A third theory is that it came from a certain Karelian man's name Prokopij, from Ruokolahti in the Middle Ages. This is the most probable explanation, supported by the Research Institute for the Languages of Finland.
