The IV Corps (Finnish: IV Armeijakunta) was a unit of the Finnish Army during the Continuation War. During the 1941 Finnish invasion of the Karelian Isthmus, it encircled three Soviet divisions in the area south of Vyborg before being renamed as Isthmus Group (Finnish: Kannaksen ryhmä).
Reconstituted in 1944, the corps was the target of the spearhead of the Soviet Vyborg–Petrozavodsk offensive. Elements of the corps fought in the decisive Battle of Tali-Ihantala at the end of the war.
