The Kozara Offensive (Serbo-Croatian: Kozaračka ofenziva/ofanziva), also known as Operation West Bosnia (German: Operation West-Bosnien) was a large-scale German-led counter-insurgency operation against the Yugoslav Partisans in the Bosnian mountain region of Kozara in the Independent State of Croatia during World War II. It was launched on 10 June 1942, with the goal to encircle and destroy the Partisans who were operating in the Kozara mountain region near Banja Luka, which threatened German access to the Belgrade-Zagreb railway.

The offensive was a coup de main operation, which utilized direct action by elements of the Wehrmacht, Home Guard and Ustaše.^[3] Poorly equipped and outnumbered, the Partisans were nearly annihilated during the fight, with only a few hundred partisans narrowly escaping as the German-NDH forces recaptured the area, including the city of Prijedor. The Germans and their allies encircled the main group and achieved their objectives after nearly 40 days of bloody combat, with heavy casualties on both sides.

The Kozara Offensive became a part of national mythology in post-war Yugoslavia, which honored the bravery and martyrdom of the Partisans.^[4] It also earned a reputation as German and NDH forces massacred Serb civilians as the battle progressed. Most of the civilians were killed during or after the battle, others were sent to concentration camps such as Jasenovac, Stara Gradiška, Sajmište, or forced labor mines in German occupied Norway where many perished.^[5]
