Milan Aćimović (Serbian Cyrillic: Милан Аћимовић; 31 May 1898 – 25 May 1945) was a Yugoslav politician and collaborationist with the Axis in Yugoslavia during World War II.

[1] On 2 September 1935, he and Velibor Jonić successfully petitioned the Ministry of Interior to legalize the Yugoslav National Movement (Zbor).

[5][6] Aćimović tried to maintain the existing state apparatus, but he had to replace officials who were not Serbs or who had left the country, as well as firing those suspected of being anti-German.

On 13 July 1941, he ordered a decree to arrest family members of communists on the run, specifically wives and sons over 16, or if they did not have children, fathers and brothers younger than 60 only if they live together.

[11] Aćimović was replaced by Tanasije Dinić as Interior Minister on 10 November 1942 because of his connections to the Chetniks, whom the Germans did not yet consider necessary or reliable allies in the fight against the Yugoslav Partisans.
