Oravais is a former municipality of Finland. It is located in the province of Western Finland and is part of the Ostrobothnia region. The municipality had a population of 2,189 and covered a land area of 203.98 square kilometres (78.76 sq mi). The population density was 10.73 inhabitants per square kilometre (27.8/sq mi). The municipality was consolidated with Vörå-Maxmo to form the new municipality of Vörå on 1 January 2011.

The Battle of Oravais from September 14 until September 15 was one of the decisive battles in the Finnish War, fought from 1808 to 1809 between Sweden and the Russian Empire as part of the wider Napoleonic Wars. Taking place in modern-day Vörå in western Finland, it is sometimes regarded as the turning point of the Finnish War: the last chance for Sweden to turn the war to her advantage. It was the bloodiest battle of the conflict, along with the Battle of Sävar, which some historians attribute to the exhaustion, resignation and desperation of the Swedish army: it was losing the war, and defeat led to its loss of Finland to Russia.
