The Åland War (, ) is the Finnish term for the operations of a British-French naval force against military and civilian facilities on the coast of the Grand Duchy of Finland in 1854–1856, during the Crimean War between the Russian Empire and the allied France and Britain. The war is named after the Battle of Bomarsund in the Åland Islands. Although the name of the war refers to Åland, skirmishes were also fought in other coastal towns of Finland in the Gulf of Bothnia and the Gulf of Finland.
