The 9th Army Corps (Ukrainian: 9-й армійський корпус) is a Corps of the Ukrainian Ground Forces.

History The corps was formed on November 19, 2022, and was first mentioned in the order of Ministry of Defense of Ukraine on November 21, 2022. It was formed as part of a start to help reform the Ukrainian military under combined arms units, which would not take a greater force until early 2025. It was formed in the city of Lutsk in Volyn Oblast, based on the money allocation and visual representation of Lyubart’s Castle in the unit’s emblem. It was reportedly created in preparation for the summer 2023 Ukrainian offensive in southern Ukraine.

The 9th Army Corps launched the first phase of a Ukrainian offensive in June 2023, when, armed with new Western military vehicles, it advanced into a well-fortified Russian defensive line, making little progress.

As of August 2025, the 9th Army Corps was responsible for the defense of the area of Pokrovsk and Myrnohrad.
