The 22nd Army Corps, (Russian: 22-й армейский корпус, romanized: 22-y Armeyskiy Korpus) was a tactical formation of the Imperial Russian Army based in the Grand Duchy of Finland before the beginning of the First World War.

After seeing much service during the war, the corps was disbanded following the October Revolution.

In 1905, as part of the ongoing re-organisation of the Imperial Russian Army's higher-up fighting review, the 22nd Army Corps was formed with its headquarters in Helsingfors, today the Finnish capital of Helsinki.

In November 1917, just after the October Revolution, the corps joined the new Western Front.
