The 20th Army Corps (Ukrainian: 20-й армійський корпус) is a Corps of the Ukrainian Ground Forces.
History The 20th Army Corps is a military unit formed as part of Ukraine's ongoing defense reforms. These reforms aim to improve command structures and operational readiness amid ongoing conflicts.
In July and August 2025, it was reported that units of the 20th Army Corps were responsible for a section of the front line from the area south of the city of Pokrovsk in the Donetsk region up to the border of the Zaporizhzhia region with the Donetsk region. In late July 2025, the corps issued statements denying that it had lost the settlements of Temyrivka and Maliivka, claiming that they were still held by its 110th and 31st Brigades, respectively. In September 2025, corps commander was removed from his post for the loss of positions in the corps' area of responsibility.
