The distance to Oulu is 105 kilometres (65 mi) to the south and to Rovaniemi is 117 kilometres (73 mi) to the northeast. It was founded in 1869 by a decree of the Emperor Alexander II of Russia because of its proximity to a deepwater port.

Kemi is situated on the Bothnian Bay, at the mouth of the river Kemijoki, and it is part of the Lapland region. The town has a population of 20,437 (31 December 2020) and covers an area of 747.28 km² (288.53 sq mi) of which 652.1 square kilometers (251.8 sq mi) are water. The population density is 214.36 inhabitants per square kilometre (555.2/sq mi).

Kemi has a claim to fame as the home of the world's largest snow castle (reconstructed every year to a different design). The SnowCastle of Kemi is usually built in the inner harbor of the city.

A model of The Crown of Finland (the original was never made for the King of Finland) is kept in the town's gemstone gallery. It also houses replicas of the Imperial State Crown of Great Britain, the scepter of the Czar of Russia, the Orbs of Denmark, and the diamond necklace of Marie Antoinette, among other items.
