The Olonets expedition (Swedish: Olonetsexpeditionen; Russian: Олонецкая экспедиция) was an invasion towards Olonets executed by Generalmajor Erik Kruse during January 1657 as part of the Russo-Swedish War of 1656–1658. Despite not capturing Olonets like he intended, Erik Kruse destroyed hundreds of buildings and killed all civilians he encountered, drawing condemnations from people like Per Brahe the Younger.
