Salla is a municipality of Finland, located in Lapland. The municipality has a population of 3,408. The population density is 0.59 inhabitants per square kilometre (1.5/sq mi). The nearby settlement of Sallatunturi is home to the Salla Ski Resort.

Salla is in the Eastern Lapland and as a border area was affected by the Second World War. Red Army troops invaded Finland at Salla during the Winter War but were stopped by the Finnish Army (see Battle of Salla). Parts of the municipality were ceded to the Soviet Union after the war. The ceded part is sometimes called "Old Salla" or Vanha Salla. During the Continuation War the old town of Salla was on the Soviet side of the border. The German XXXVI Corps attacked the Soviet positions in an operation code-named Polarfuchs. With the help of the Finnish 6th Division it managed to occupy all of the ceded territories. At the end of the war the German troops were pushed out of Lapland by Finnish troops in the Lapland War.

In January 2021, the mayor of Salla, Erkki Parkkinen, launched a bid to host the 2032 Summer Olympic Games to raise awareness of climate change and highlight the threat the climate crisis poses to Salla and its ecosystem, which is dependent on low temperatures for most of the year.
