St. Nicholas Cathedral is the main church of the Kuopio Orthodox Parish in Väinölänniemi, Kuopio, Finland, and also the seat of the Orthodox Diocese of Karelia. The church was completed in 1903 and is dedicated to Saint Nicholas. The church, built between 1902 and 1903, was designed by the master builder Aleksander Isakson from Vyborg. The facade is plastered and painted to look like red brick, but there is also genuine brick under the plaster. In appearance, it resembles red-brick simultaneous garrison churches. The iconostasis was made at the Alexander Nevsky Lavra in Saint Petersburg and was donated by Nikolay Bobrikov, the Governor-General of Finland. There are eight bells in the cathedral.
