The Aćimović Offensive, also known as the Aćimović Pursuit, was a military operation of the Serbian State Guard and Chetniks of Kosta Pećanac against partisan detachments in Southeastern Serbia. It was named after Milan Aćimović, the Minister of Internal Affairs in the collaborationist government of Milan Nedić, who was entrusted with preparing the offensive. Occupation troops (German and Bulgarian) did not directly participate in the operation; it was entirely entrusted to collaborationist units.

This was one of the most organized and largest offensives against partisan forces in Šumadija, Eastern and Southern Serbia, involving about 10,000 collaborationist troops (Pećanac's Chetniks, the Serbian State Guard, and the Serbian Volunteer Corps).

In the third stage of the offensive, which began on 10 August 1942, the Rasina, Toplica and Jablanica detachments were targeted, followed by the Leskovac and Babič detachments. Around 20 September 1942 the Aćimović Offensive ended. Its results were mixed: many fighters of the Babič Detachment perished, but the unit nevertheless survived.
