The IV Corps was a corps-level formation of the Royal Hungarian Army which saw extensive action on the Eastern Front during World War II.

The Corps was created on 1 October 1938 from mixed brigades, as a direct result of the then Prime Minister Kálmán Darányi announcing rearmament (Győri Programme [hu]) on 5 March 1938.

In April 1942, the IV Corps became part of the Second Hungarian Army and was sent to the Eastern Front where it arrived in July 1942.

It participated in Case Blue and advanced towards the Don River where it dug in for the coming winter around the area of Korotoyak, Voronezh Oblast .

On 19 September 1944, the staff personnel of the Corps Headquarters was used to form a new Third Army, of which József Heszlényi also became commander.
