Mijo Babić (1 September 1903 – 3 July 1941), nicknamed Giovanni, was a deputy of the Croatian fascist dictator Ante Pavelić, and the first commander of all concentration camps in the Independent State of Croatia.

[3] On 22 March 1929, Babić, Zvonimir Pospišil, Marko Hranilović, Matija Soldin murdered Toni Šlegel, the chief editor of Novosti and president of Jugoslovenska štampa, in Zagreb.

[4] At that time, Babić was a chauffeur for the Siemens plant in Zagreb and, according to official reports, he murdered one and wounded another of the policemen who came to arrest him, and managed to escape.

While he was in Italy, the Ustaše spent years planning for a genocidal campaign in their native country and trained a small band of followers for a takeover.

In January 1938, the Italian authorities intercepted a letter addressed to Pavelić from Babić and Ljubomir Kremzir outlining a plan to secretly return to Yugoslavia and carry out various terrorist attacks—including the assassinations of prime minister Milan Stojadinović and prince regent Paul—with the aim to "trigger the revolution in Croatia".

Against Pavelić's order, Babić brought several trucks of Ustaše from Zagreb to massacre 520 Serb peasants in the region of Kordun, where they had lived together with Croats for many centuries.
