Savolax and Karelia County (Swedish: Savolax och Karelens län, Finnish: Savonlinnan ja Karjalan lääni) was a county of Sweden 1775–1809 and province of Grand Duchy of Finland 1809–1831. It was formed in 1775 when Savolax and Kymmenegård County was divided into Savolax and Karelia County and Kymmenegård County. Residence city was Kuopio.
By the Treaty of Fredrikshamn in 1809 Sweden ceded all its territories in Finland, east of the Torne River, to Russia. Savolax and Karelia Province was succeeded in 1831 by the Kuopio Province in the autonomic Grand Duchy of Finland. Minor parts of province were merged to Mikkeli Province.
